Patent number: 4331304Abstract: An emergency lock type retractor for a passive safety belt assembly of a vehicle includes a housing (1) mounted on the vehicle body, a reel (3) for the belt (4) rotatably supported by the housing and a ratchet wheel (7) secured to the reel. An inertia device (16) detects an emergent deceleration of the vehicle and causes a pawl (9) to engage with the ratchet wheel to lock the reel and prevent unwinding of the belt. The inertia device includes a first inertia member (19) perpendicularly suspended by the housing to assume a constant angle with respect to the vehicle body. The first inertia member supports a more sensitive second inertia member (22) which displaces relatively to the first inertia member as the vehicle is emergently decelerated. When the mounting angle of the housing varies with respect to the vehicle body, the first inertia member swings to stably maintain the second inertia member at a constant angular position with respect to the vehicle body.Type: GrantFiled: September 8, 1980Date of Patent: May 25, 1982Assignee: Nissan Motor Co., Ltd.Inventors: Hideoki Matsuoka, Yoshimi Yamamoto

Patent number: 4326667Abstract: An air conditioner of an automatic temperature adjusting type used particularly for controlling the air temperature within a passenger compartment of an automotive vehicle. According to the present invention, the air conditioner controls simultaneously the air flow rate of a fan providing the air supply, and an air mixing door which controls the flow of air through either a heater or a bypass around the heater. The control is such that over an intermediate portion of the adjustment range the fan and air mixing door are operated together whereas at end portions of the adjustment range the fan is adjusted without moving the air mixing door. This is achieved by use of a particularly convenient gear mechanism of novel design.Type: GrantFiled: December 18, 1980Date of Patent: April 27, 1982Assignee: Nissan Motor Company, LimitedInventors: Yukiho Murata, Yasushi Inoshita
