  • Patent number: 4487452
    Abstract: A rotatable seat for a multi-passenger automotive vehicle employs a latch mechanism releasable only by manual operation of an actuating lever. The latch mechanism includes latch-and-hook assemblies at both the front and rear of the seat to prevent inadvertent rotation of the seat. In addition, the seat rotation is governed by a cam having deep recesses at the two normal sitting positions. The cam is designed with sloping faces so that the weight of the seat drives rotation towards the normal positions. An additional safety mechanism prevents rotation of the seat unless the seat back is in a position preventing passengers from sitting thereon.
