ABSTRACT:
A vehicle seat is mounted on a platform that is pivotally mounted to the vehicle frame for movement between a lowered, operating position and a fully raised, non-use position. A holdup mechanism is coupled between the underside of the platform and the frame and includes a prop link having an end received in a guide slot provided in a bracket secured to the platform. The guide slot defines a plurality of notches therealong and a spring urges the prop link so its end will automatically enter an adjacent notch upon releasing the platform during lifting or lowering the platform to or from its fully raised position. A release mechanism is provided for moving the prop link against the action of the spring so as to permit the platform to be lowered.
