Abstract
This invention relates to a seat assembly especially suitable for use on a front seat of a two door vehicle and particularly relates to a comfort adjustment manual override seat track assembly for permitting, seat position adjustment, and the seat to slide forward to permit access to behind the seat and return to its initial position.
Claims52
A comfort adjustment manual override seat track assembly suitable for securing a seat to the floor of a vehicle to permit the seat's position to be adjusted relative to the front of the vehicle and permit the seat to be moved from that adjusted position towards the front of the vehicle to permit maximum access to behind the seat and to be returned to that adjusted position, the assembly comprising:
- (a) a pair of laterally spaced tracks and supports therefor for being secured to the vehicle, at least one of the tracks and supports carrying a plurality of apertures along its length;
- (b) a fastener slideably secured to at least one of the track and associated supports carrying the plurality of apertures for slideable movement relative thereto and for being removeably secured thereto by extending into at least one aperture precluding longitudinal movement with respect to the track and associated support of the fastener until deliberately disengaged therefrom;
- (c) means to engage and disengage each such fastener from the at least one aperture of the track and associated supports;
- (d) a slide secured to each track and support to which each fastener is slideably secured for relatively longitudinal movement with respect thereto and for being secured to the bottom of the seat, each slide carrying a depending trap, the trap comprising a pair of spaced walls, a forward wall and a rear wall, the forward wall being closest to the front of the vehicle in which the assembly is mounted and being fixed relative to the slide and the rearward wall being displaceable from a normally trapping position with the front wall to trap the associated fastener between the walls, to a position whereat the rearward wall of the trap does not trap the fastener to permit the slide to travel forward, the motion of the displacement of the rearward wall of the trap being in a plane parallel to the direction of movement of the slide, the rearward wall sloped in such a manner to permit the fastener to be wedged between the forward and rearward walls when trapped, yet provides sufficient clearance to permit the wall to move to the position whereat the rearward wall of the trap does not trap the fastener to permit the slide to slide forwardly;
- and
- (e) means to maintain the rearward wall in normally trapping position to trap the fastener between the spaced forward and rearward walls until the rearward wall is displaced to a position at which it does not trap the fastener thus permitting the slide to travel forwardly.
A comfort adjustment manual override seat track assembly suitable for securing a seat to the floor of a vehicle to permit the seat' s position to be adjusted relative to the front of the vehicle and permit the seat to be moved from that adjusted position towards the front of the vehicle to permit maximum access to behind the seat, and to be returned to that adjusted position, the assembly comprising:
- (a) a pair of laterally spaced tracks and supports therefor for being secured to the vehicle, each track and support carrying a plurality of apertures along its length on the side of the track closest to the other track;
- (b) a fastener slideably secured to each track and associated support for slideable movement relative thereto and for being removeably secured thereto by extending into at least one aperture precluding longitudinal movement with respect to the track and associated support of the fastener until deliberately disengaged therefrom;
- (c) means to engage and disengage each such fastener from the at least one aperture of the track and associated support;
- (d) a slide secured to each track for relative longitudinal movement with respect thereto and for being secured to the bottom of the seat each slide carrying a downwardly extending depending trap from the side of the slide closest the opposite slide and extending downwardly along the side of the track and associated support in which the plurality of apertures are provided, the trap comprising a pair of generally downwardly extending longitudinally spaced walls, a forward wall and a rearward wall, the forward wall being closest to the front of the vehicle in which the assembly is mounted and being fixed relative to the slide and the rearward wall being displaceable from a normally trapping position with the front wall to trap the associated fastener between the walls to a position whereby the rearward wall of the trap does not engage the fastener to permit the slide to slide forwardly, the motion of the displacement of the rearward wall of the trap being in a plane parallel to the direction of movement of the slide, the normally downwardly extending rearward wall sloped in such a manner from its upper end to its lower end away from the fastener to permit the fastener to be wedged between the forward and rearward walls when trapped yet provides sufficient clearance to permit the wall to move to the position whereat the rearward wall of the trap does not trap the fastener to permit the slide to travel forward;
- and
- (e) means to maintain the rearward wall normally in a downwardly extending trapping position to trap the fastener between the longitudinally spaced walls but which permits the rearward wall to be moved to a position to free the fastener from its trapped position.
