ABSTRACT:
An adjustment mechanism for a car seat provides multiple vertical locking positions for adjusting the attitude of a seat with respect to an automobile seat cushion and back. The car seat has a base with forward and rear support walls each having a key way matching the profile of the stem portion of a locking plunger. The plunger has a forward handle portion and a pair of shoulder portions extending to the rear of the plunger which engage mating recesses in a key way formed in an adjustable support member. The adjustable support member is slidably arranged between the forward and rear support walls of the base. The plunger is spring biased by a spring mounted in a spring aperture formed in the rear of the plunger stem. The relative positions of the support member and the car seat base are adjusted by withdrawing the plunger until the shoulder portions clear the support member key way, adjusting the position of the support member with respect to the car seat base and releasing the plunger to enable the spring to force the plunger rearwardly into the support member key way.
