Patent number: 4449752Abstract: A seat position control mechanism with a neutral position return mechanism for a front seat of a vehicle such as two-door sedan or hard top sedan incorporates a memory plate disposed outside the locking teeth of the locking plate of the seat slide adjusting device, a rockable lever journaled with the maneuverable shaft rockably secured to the locking lever, and connecting means connected from the rockable lever to the back rest of the front seat, in addition to the ordinary seat slide adjusting device. The rockable lever is always urged by the rotating force of the torsion spring in the seat locking direction so that the maneuverable shaft can be locked or unlocked regardless of the rockable lever. Thus, the entire mechanism is low bulky, compact and light with simple construction, and the front seat can be smoothly slid without interference with the rockable lever and other members.Type: GrantFiled: September 27, 1979Date of Patent: May 22, 1984Assignee: Toyota Jidosha Kogyo Kabushiki KaishaInventors: Jun Yasumatsu, Mamoru Mori, Toshihito Nishiwaki, Akira Owada
