Abstract

Abstract An auxiliary chair for use in restraining young children in vehicles. The chair is capable of either frontward or backward orientation and in each case the portion thereof that engages the seat belt of the vehicle remains in the same relative position. The engagement portion is on an engagement arm that is movable between a frontward and a rearward position, and in each position locks both the chair body and the chair base thereto for security. The chair is tiltable to several orientations and is locked into several tilt positions via a shaft through the body that rides in a slot within locking plates in the base. The locking plate locks the position due to springs forcing the plates upward. The lock is easily released by handles on the sides of the base.
