A pneumatic piston and cylinder asmbly is pivoted at one of its ends to the U-shaped lap bar and pivoted at its other end to a support bracket at a point thereon spaced with respect to a center line of the lap bar to which it is attached so that movement of the lap bar moves the piston to compress gas in the cylinder whereby pressure in the pneumatic cylinder holds the lap bar in restraint in lower position and in elevated position.
