摘要： A wheel chair restraint system and apparatus. The system includes a foldable seat having a bottom connected to a seat back for movement about a pivot axis between a lowered position and a raised position. The apparatus has a frame base connected to a lower surface of the seat bottom. First and second parallel lock pin supports extend from the frame base and have aligned bores for receiving a lock pin. A guide plate extends from the frame base and cooperates with the first lock pin support to define a space for receiving the wheel to be restrained. The lock pin is movable by a first spring from a retracted position to an engaged position in which the lock pin is supported by the lock pin supports and has a first end protruding beyond the first lock pin support to restrain movement of a wheel. A lever is provided for moving the lock pin back into its retracted position to allow release of the wheel. An interlock plate has a first portion secured to the first lock pin support for movement between a blocking position holding the lock pin in its retracted position and a release position spaced from the bore of the first lock pin support. A second portion of the interlock plate is positioned in the space in such manner that a wheel inserted into the space moves the interlock plate, against the force of a second spring, into its release position so that the lock pin automatically moves into its engaged position.
