Description

TECHNICAL FIELD

This disclosure relates generally to door retention systems for motor vehicles. More particularly, the disclosure relates to a window frame-mounted lateral retention system for a vehicle door.

BACKGROUND

Ejection mitigation regulations typically require vehicles to pass a test comprising propelling an impactor from an interior of a vehicle towards the vehicle windows. To pass, an ejection mitigation safety system must prevent the impactor from moving past a specified distance beyond a vertical plane defined by the vehicle window. For fixed windows and smaller doors, inclusion of laminated glass in addition to the door structure often suffices to pass an ejection mitigation test.

However, for larger doors such as sliding vehicle doors, the door structure may lack the required structural stiffness and integrity to prevent the impactor from moving beyond the specified distance. Accordingly, there is a need for supplemental ejection mitigation measures to satisfy ejection mitigation requirements for such larger doors.

To satisfy this identified need in the art, the present disclosure relates to an auto-locking lever lock system disposed between the vehicle body and a sliding door window frame. This system provides an additional attachment point between the vehicle body and the sliding door window frame. Advantageously, the disclosed auto-locking lateral impact retention system holds the door to the vehicle body side under a normal load with respect to a plane defined by the door longitudinal and vertical axes. When subjected to a sufficient impactor impact, the auto-locking lateral impact retention system prevents the impactor from displacing the sliding door window frame beyond a specified distance from the vehicle body side.

SUMMARY

In accordance with the purposes and benefits described herein, in one aspect a a lateral impact retention system for a vehicle door is described, comprising a door window frame retainer configured for mounting to the vehicle body and a pivoting catch configured for mounting to a window frame of the door and to engage the retainer when the door is subjected to a door-displacing lateral impact. Advantageously, the operation of the pivoting catch is independent of any door-operating mechanism of the door. In use, the pivoting catch automatically inserts into the retainer when the door is translated to a fully closed position and automatically displaces from the retainer when the door is translated towards an open configuration.

In embodiments, the pivoting catch comprises a retaining flange which engages a cooperating retainer slot when the door is subjected to the door-displacing lateral impact. The pivoting catch may also comprise a cam surface which slidingly displaces the pivoting catch from the retainer when the door is translated towards the open configuration. The retainer may include a cooperating surface which urges the pivoting catch into a recess disposed in the door when the door is translated towards the open configuration. In embodiments, a biasing member urges the pivoting catch outwardly from the recess. In embodiments, the lateral impact retention system is configured for a vehicle sliding door.

In other aspects, vehicles comprising the lateral impact retention system are described.

In the following description, there are shown and described embodiments of the disclosed auto-locking lateral impact retention system. As it should be realized, the device is capable of other, different embodiments and its several details are capable of modification in various, obvious aspects all without departing from the devices and methods as set forth and described in the following claims.

DETAILED DESCRIPTION

To address the foregoing and other identified problems, the present disclosure describes an auto-locking lateral impact retention system provided by a vehicle body side-mounted retainer and a sliding door-mounted pivoting catch. Advantageously, during normal operation of the vehicle sliding door the pivoting catch automatically inserts into and displaces from the retainer. However, on receiving a suitable lateral impact sufficient to displace the door window frame from the vehicle body side, the pivoting catch engages the retainer to prevent the sliding door from displacing away from the vehicle body side.

In greater detail, as shown in FIG. 1A, during normal use a vehicle 100 sliding door 102 engages a track (not shown) associated with the vehicle body 104, allowing the door to slide along the vehicle x-axis between an open and a closed configuration (see arrows A). During such normal operation, the sliding door 102 and associated window frame 106 remain in alignment with the vehicle body side (FIG. 1B). However, on receiving a sufficient lateral impact from an impactor I, a portion of the door 102 structure may bend and at least the door window frame 106 may displace from the vehicle body side 104 (see FIG. 1C).

To solve this and other problems, the present disclosure describes a lateral impact retention system for a vehicle sliding door. At a high level, the described system includes a vehicle body-mounted retainer and a sliding door-mounted catch which, on receiving a sufficient door-displacing impact, engages the retainer to prevent lateral displacement of the door.

In an embodiment (see FIG. 2), the vehicle body-mounted retainer 200 comprises a body 202 defining an interior receiver 204. One wall of the body 202 defines a ledge or lip 206. Another wall of the body 202 defines a catch-displacing surface 208. As will be described in greater detail below, the interior receiver 204 is dimensioned to receive a portion of a door-mounted catch therein. In use, the vehicle body-mounted retainer body 202 is disposed at least partially recessed into a portion of the vehicle body surface 104.

With reference to FIGS. 3A-B, a sliding door-mounted pivoting catch 300 comprises a catch body 302 including at least one cam surface 304. An aperture 306 is provided, dimensioned to receive a pin 308 there-through to allow a pivoting motion of the catch 300. The catch body 302 further includes a stopper 310, to which a biasing member 312 such as a torsion spring, a clock spring, or other suitable biasing member is attached at a first end. The biasing member 312 is attached at an opposed end to a fixed stopper 314 which is in turn attached to a portion of the vehicle sliding door 102 (not shown). By this disposition of the biasing member 312, it will be appreciated that the pivoting catch body 302 is continuously urged upwardly in a vehicle z-axis direction, away from the sliding door window frame 106. However, the catch body 302 can pivot about the fixed axis provided by pin 308 upwardly and downwardly (see arrow B). The catch body 302 further includes or defines a flange 316, configured to engage the door-mounted retainer body interior lip 206 as will be described.

As shown in FIG. 4, the body-mounted retainer 200 is disposed in a portion of the vehicle body 104, and the sliding door-mounted pivoting catch 300 is disposed in a portion of the sliding door window frame 106, in an aligned arrangement whereby the pivoting catch 300 will automatically insert into the body-mounted retainer 200 when the sliding door 102 is translated to a closed configuration (see arrow A).

In greater detail, as shown in FIGS. 5A-C as the sliding door 102 is translated to the closed configuration, the door-mounted pivoting catch 300 approaches the vehicle body-mounted receiver 200 (FIG. 5A), and the catch cam surface 304 contacts the retainer catch-displacing surface 208 whereby the pivoting catch 300 is pivoted (arrow B) into a recess 500 defined in the sliding door window frame 106, compressing biasing member 312.

As the sliding door 102 reaches the fully closed configuration (FIG. 5C), biasing member 312 urges the door-mounted pivoting catch 300 to insert into the interior receiver 204. Likewise, as will be appreciated by the skilled artisan, when the sliding door 102 is urged towards the open configuration, the reverse process will occur, i.e. the retainer catch-displacing surface 208 will urge the pivoting catch 300 into the recess 500 by way of cam surface 304. Thus, simply opening and closing the sliding door 102 normally will cause the door-mounted pivoting catch 300 to insert into and displace from the body-mounted retainer 200.

With reference to FIG. 6A-B, under normal operation door-mounted pivoting catch 300 is inserted into and displaced from the vehicle body-mounted retainer 200 as described above (FIG. 6A). However, on receiving a suitable door-displacing lateral impact (arrow C), as shown in FIG. 6B the flange 316 of pivoting catch 300 engages the body-mounted retainer ledge or lip 206, automatically locking the sliding door in place and preventing full lateral displacement of the sliding door window frame 106.

Accordingly, by the foregoing description a lateral impact retention system for a vehicle sliding door is provided. Advantageously, the described lateral impact retention system for a vehicle sliding door includes a sliding door-mounted catch which automatically engages and releases a vehicle body-mounted retainer, simply by normal opening and closing operations of the sliding door. In turn, the mechanism is uncomplicated, robust, and does not require any element of the sliding door latching, locking, door handle, or other door operating mechanisms for operation.

Obvious modifications and variations are possible in light of the above teachings. For example, the foregoing description primarily describes the lateral impact retention system in the context of a sliding door for a vehicle. However, the skilled artisan will appreciate that the described system is readily adaptable to any vehicle door type, including sliding doors, swing-out doors, gull-wing doors, and others. All such modifications and variations are within the scope of the appended claims when interpreted in accordance with the breadth to which they are fairly, legally and equitably entitled.
