Abstract
A single pivot connection for a legrest of a vehicle seat and the like includes a shaft extending from a bracket attached to the seat and an arm bracket attached to the legrest and pivotally supported upon the shaft. The arm bracket has a cylindrical portion and there is a hub on the end of the cylindrical portion with a circumferentially extending notch therein which receives a key formed in an annular member rotatably positioned upon the hub. A gear mounted on the shaft is engageable with a pawl and there is a braking disc between the end of the cylindrical portion and gear such that the application of a predetermined force on the legrest will pivot the legrest with respect to the seat. The pawl engages the gear as the legrest pivots to a horizontal position and pivoting beyond the horizontal to the vertical up position causes cam surfaces on the annular member to disengage the pawl from the gear so that the legrest is free for pivotal movement.
