Patent number: 4717089Abstract: A webbing retractor for use in an occupant restraining seatbelt system for a vehicle includes a lock wheel supported on one end portion of a webbing take-up shaft and an acceleration sensor. When an emergency situation of the vehicle occurs, the lock wheel and the acceleration sensor are engaged with each other, thereby causing a lock bar to be engaged with a ratchet wheel rigidly secured to the take-up shaft, and thus locking the take-up shaft from rotating in a direction in which the webbing is unwound. The lock wheel and the lock bar are connected together through a friction member by a predetermined frictional force. Accordingly, even when the lock wheel and the acceleration sensor are still engaged with each other after an emergency situation of the vehicle has ceased, the webbing can be unwound from the take-up shaft with a force which is greater than the predetermined frictional force.Type: GrantFiled: July 8, 1986Date of Patent: January 5, 1988Assignee: Kabushiki Kaisha Tokai-Rika-Dinki-SeisakushoInventor: Keiichi Tamura

Patent number: 4667894Abstract: A webbing lock apparatus for use in a vehicle has a U-shaped frame, and a webbing take-up shaft rotatably supported by a shaft carriage. The carriage is pivotally mounted on the frame and biased toward one direction. When an emergency situation of a vehicle occurs, a ratchet is activated so as to lock the take-up shaft and to cause the shaft carriage to pivot on the frame in another direction as a result of the webbing tension. This movement causes the webbing wound around the take-up shaft to abut against a fixed pressing member also mounted on the frame. In consequence, the amount of webbing wound off of the take-up shaft in an emergency situation of the vehicle is minimized.Type: GrantFiled: September 30, 1985Date of Patent: May 26, 1987Assignee: Kabushiki Kaisha Toka-rika-denki-seisakushoInventors: Shingo Izuchi, Keiichi Tamura, Shinji Mori
