Patent number: 6824167Abstract: A seat belt system which does not interfere with the ingress and egress of rear seat passengers, and can detect the presence of an occupant without being influenced by the seat belt tension to provide the accurate weight detection. In one embodiment, the seat belt system comprises a retractor disposed in the rear door, an anchor of the seat belt webbing, and a rail member that allows the anchor of the seat belt webbing to slide in the vehicular longitudinal direction. The front end of the rail member is attached substantially on the seat side above a weight detecting device. The weight detecting device is disposed between the front seat and the floor panel, while the buckle capable of engaging the tongue of the seat belt webbing is disposed on the seat above the weight detecting device.Type: GrantFiled: February 12, 2003Date of Patent: November 30, 2004Assignee: Mazda Motor CorporationInventors: Yousuke Nishimoto, Takayuki Seto, Kenji Muramatsu, Hiroaki Nakao

Patent number: 4420783Abstract: A mode selector assembly for use in a tape recorder or the like is disclosed herein, for placing the tape recorder or the like into a selected operating mode by means of a rotating member upon the actuation of an actuator lever. The mode selector assembly includes a cam surface on the rotating member, interlocking device provided between the actuator lever and the rotating member for sliding movement with rotating movement of the cam surface, responsive to rotation of the rotating member and connecting means for connecting the actuator lever to the interlocking means. The actuator lever is shifted to its actuated position via the interlocking means in response to rotation of the cam surface immediately after the rotating member is rotated upon actuation of the actuator lever.Type: GrantFiled: July 7, 1981Date of Patent: December 13, 1983Assignee: Sharp Kabushiki KaishaInventors: Takahiko Suezawa, Satoru Koizumi, Hiroaki Nakao, Takashi Tsuchitani

Patent number: 4404610Abstract: A mode selection assembly for use in tape recorders or the like is disclosed which includes a rotating member (for example, a gear) rotatable in an intermittent manner and bearing a plurality of projections, a plurality of actuator levers for selection of the operating modes of the tape recorder or the like, a plurality of engaging members one of which engages with one of the projections in response to actuation of the actuator levers. The rotating member is prevented from rotating to bring the tape recorder or the like into a desired one of the operating modes when one of the projections is held in engaging relationship with one of the engaging members and the rotating member is permitted to rotate for selection of another operating mode when none of the projections are in engaging relationship with the engaging members.Type: GrantFiled: April 14, 1981Date of Patent: September 13, 1983Assignee: Sharp Kabushiki KaishaInventors: Satoru Koizumi, Hiroaki Nakao, Takashi Tsuchitani
