  • Patent number: 10406870
    Abstract: This invention discloses an automatic locking device for snow anti-skid chains. Wherein the snow anti-skid chain comprises a ratchet wheel lock catch and a anti-skid chain; the anti-skid chain is respectively fixed at the buckle and the outer part of the housing aforesaid, and extends towards three directions. The ratchet wheel lock catch is used to make the anti-skid chain to attach to automobile tires firmly and is controlled by pressing two buttons on its lower side, which is different from existing operational actions of braking off and twisting. The pressing action is simple and available for one hand operation. The overall structure is simple and reliable, conforming to use habits of control actions by users.

  • Patent number: 9283930
    Abstract: In a webbing take-up device, a cut-out portion is formed in a close-off portion that closes off a pawl housing groove from a side opposite a spool body side. For this reason, the close-off portion is not formed in a position facing ratchet teeth which is at from a second ratchet tooth from a take-up direction side to the other side. Due to this, even if a head portion of a lock pawl, particularly a take-up direction side portion of the head portion, is displaced in such a way as to move away from the spool body, the head portion does not come into contact with the close-off portion or, even if the head portion comes into contact with the close-off portion, a force with which the head portion presses the close-off portion becomes smaller.

  • Patent number: 9242617
    Abstract: A seat belt retractor with a speed-controlled load limiting device has a belt shaft pivot-mounted in a retractor frame, a blocking device for locking the belt shaft relative to the retractor frame) in the belt extraction direction when a predetermined value of the belt webbing extraction acceleration and/or of vehicle deceleration is exceeded, and at least two toothed elements which, upon activation of the load limiting device move relative to each other. One of the toothed elements performs an oscillatory motion, wherein both parts feature teeth, with which they alternately engage and disengage during the relative motion belt shaft has a first and a second part. The second part can be locked relative to the retractor frame, and each of the toothed elements is allocated to a different part of the belt shaft.

  • Publication number: 20130154337
    Abstract: During an emergency, in one form of a retractor having a spool, external teeth of a pawl provided at a spool right side end are made to mesh with some of internal teeth provided on a frame, and, with load acting on a seat belt, a spool left side end is brought into contact with a spool pushing portion. Since the spool left side end tends to be moved further in a direction of seat belt load with the load acting on the seat belt, the spool pushing portion pushes the spool left side end, whereby some of external teeth come into contact with internal teeth provided on the frame and fit deeply into gaps between adjacent ones of the internal teeth. Thus, some of the external teeth of the spool effectively come into mesh with the respective internal teeth of the frame with a simple movement of the spool.

  • Patent number: 6732968
    Abstract: Disclosed is a seat belt pretensioner for a vehicle wherein a spool is mounted in such a way that it cannot be further released at the onset of a car accident but can push itself downwardly in a fixed state along the length-wise direction of a retractor and thus can effectively rewind a seat belt with ease. To serve this purpose the seat belt pretensioner of the present invention comprises a retractor cover wherein sliding guides are mounted both on right and left sides, a spool mounted in such a manner that a seat belt is wound up with an elastic support and is able to slide along the sliding guide, and a piston structure, being mounted on the upper part of said cover, pushes said spool downwardly by the explosion force of explosives.
