Abstract: A wheelchair lift device located in a bus stepwell that includes foldable hinged sections normally positioned through a first linkage to form a step with a riser and in which the first linkage operates during deployment to control forward swinging movement of the sections to form a platform for supporting a wheelchair that can be lowered to ground level by a second linkage.

Abstract: A bifold door assembly for an access port in a vehicle having a non-linear side wall. The assembly includes a pair of bifold doors, each having a planar outer panel disposed in a plane between an upper overhang and lower stepwell which extend outwardly of the vehicle side wall. The proximate edges of the outer panels seal to each other at the center of the access port and the distal edge of each is pivoted to a coplanar outer portion of a side panel. Each side panel has an inner planar portion pivotally attached to the vehicle interior and an intermediate portion of arcuate cross-section which runs from the outer portion to the inner portion closely past a respective side wall of the access port and in engagement with a seal. The outer panel is guided by a guide track on the overhang and a door operator pivots each side panel to fold the outer panel toward the side panel and inwardly of the access port.

Abstract: An axle attachment for a vehicle having an axle housing disposed transversely of the vehicle and a control arm supported on the vehicle for pivotal movement about a first transverse axis, the attachment including a flange on the axle housing disposed between spaced parallel surfaces on the control arm, a bolt supporting the flange on the control arm for pivotal movement about a second transverse axis, a pair of apertures in the flange at first and second radial distances from the second axis and angularly spaced by a first angle of separation, and two pairs of aligned apertures in the spaced parallel surfaces at radial distances equal to the first and second radial distances and spaced angularly by a second angle of separation exceeding the first so that registry between the apertures in the flange and corresponding ones of the pairs of apertures in the parallel surfaces occurs at different relative angular orientation between the axle housing and the control arm.
