Abstract:
1. A vehicular arm rest comprising: a fixed axle extending along an axis; a primary part rotatable about the axis on the axle, axially fixed on the axle, and formed with an array of axially directed primary-part teeth; an arm-rest body fixed to the primary part and pivotable therewith about the axis in an downward direction between a raised position and a lowered position and in an opposite upward direction between the lowered position and the raised position; a secondary part at most limitedly pivotal about the axis on the axle, axially shiftable on the axle, and having an array of axially directed secondary-part teeth meshable with the primary-part teeth, the teeth of both parts being angled such that when meshed the primary-part and secondary-part teeth inhibit movement of the arm-rest body in the downward direction between the raised position and the lowered position but permit movement of the arm-rest body in the upward direction between the lowered position and the raised position; an abutment axially fixed on the axle with the secondary part between the abutment and the primary part; a spring assembly braced axially between the abutment and the secondary part and urging the secondary-part teeth into mesh with the primary-part teeth; and a controller including for pushing the secondary part away from the primary part on pivoting of the primary part in the downward direction from the raised position of the arm-rest body toward the lowered position for decoupling the primary-part teeth from the secondary-part teeth and for coupling the primary-part teeth with the secondary-part teeth and preventing further movement in the downward direction on reaching the lowered position.
