  • Patent number: 4938520
    Abstract: A completely mechanical hold open device for a swingably mounted vehicle closure includes a pair of telescoping members pivotally connected to the closure and vehicle body and a releasable latching means for automatically holding the telescoping members in an extended position and hence the closure in its open position. The latching means is constructed such that it can be automatically released by merely exerting a downward force in excess of a predetermined magnitude on the closure to move the latter to its closed position.
    Type: Grant

  • Patent number: 4607877
    Abstract: A vehicle body panel arrangement includes a first panel having a bight portion provided with a terminal flange and a second panel having an edge portion resiliently held against the flange of the first panel by a deflectable portion of a clip mounted to the first panel. The clip also includes an abutment adjustable relative to the flange of the first panel to define a throat guiding insertion of the edge portion of the second panel into engagement with the flange of the first panel.

  • Patent number: 4474402
    Abstract: A compressible weatherstrip includes a mounting portion adapted for attachment on the vehicle body and a tubular deflection portion integrally molded with the mounting portion and having a sealing face adapted for engagement by the closure panel upon movement of the closure panel to the closed position. A feeler portion is integrally molded with the tubular deflection portion and is adapted to engage with a flange of the body panel defining the vehicle body opening and deflect the tubular body portion to an adjusted angular orientation so that the sealing face is automatically adjusted to a certain vertical position irrespective of a variation in the vertical position of the weatherstrip mounting portion. Accordingly, the sealing face is reliably poised at a precisely adjusted position which will provide a consistently reliable magnitude of weatherstrip compression upon closure of the closure panel.

  • Patent number: 4458379
    Abstract: A closure panel hinge and hold open mechanism includes a hinge bracket adapted for mounting on a vehicle body and a closure panel bracket. A pivot shaft pivotally mounts the closure panel bracket on the hinge bracket. A coil spring surrounds the pivot shaft and has integral first and second spring legs extending outwardly from the endmost spring coils thereof and respectively anchored on the hinge bracket and the closure panel bracket to urge the closure panel to a normal closed position relative the hinge bracket. A detent shoulder is provided on the hinge bracket and is automatically engaged by the second spring leg anchored on the closure panel when the closure panel bracket is moved from the closed position to the open position to hold the second spring leg against return movement and thereby hold the closure panel in the open position.
