  • Publication number: 20140217787
    Abstract: To provide a vehicle seat structure in which, when a pretensioner operates, parts at a pretensioner side interfering with parts disposed at a side of a seat cushion is suppressed. A vehicle seat structure has: a three-point seatbelt device that is configured to restrain a passenger by a shoulder webbing and a lap webbing; a lap outer side pretensioner that is connected to a distal end side portion of the lap webbing at a vehicle transverse direction outer side with respect to a seat cushion, and that is fixed to an upper rail, and that, when a vehicle collision is detected or predicted, forcibly applied tension to the lap webbing; and an outer shield that covers, from a vehicle transverse direction outer side, the seat cushion together with the lap outer pretensioner and a portion of the lap webbing which portion includes a region connected to the lap outer pretensioner.

  • Patent number: 8684469
    Abstract: A vehicle seat belt apparatus includes: a webbing; a lap anchor to which one end portion of the webbing is fixed and that is pivotable in a vehicle longitudinal direction; and a position retaining member that allows the webbing to be slidably inserted therethrough, and that is rigid in the vehicle longitudinal direction and is flexible and elastic in a vehicle transverse direction. In a seat belt retracted state, the position retaining member extends obliquely forward and upward from a lower end portion, and an upper end portion is located ahead of a side support of a seat back and above a seat shield.

  • Patent number: 8662537
    Abstract: A dilatant characteristic portion, that is structured to include a dilatant characteristic resin material, is provided at a portion of a webbing from a lap webbing portion to a portion that is further toward a shoulder webbing side than a through-hole of a tongue in a webbing applied state. When the webbing is pushed against an inner peripheral portion of the through-hole due to a body of a passenger pulling the webbing when a vehicle suddenly decelerates, the dilatant characteristic resin material hardens due to this load. Due thereto, flexure of the webbing when the webbing attempts to pass-through the through-hole and move is restricted, and therefore, the shoulder webbing passing-through the through-hole and moving toward a waist portion side of the passenger can be prevented or suppressed.

  • Patent number: 8240712
    Abstract: A shoulder anchor device is provided with a shoulder anchor (38) in which is formed an insert-through hole (40) through which a webbing (24) is inserted, and a slide plate (50) covering a vehicle cabin interior side of the shoulder anchor. A gap between an upper edge portion (52a) of an opening portion (52) at the slide plate (50) and a supporting region (42) that supports the webbing (24) at the shoulder anchor, is such that A>B where A is a gap dimension at a front portion side in a vehicle longitudinal direction and B is a gap dimension at a rear portion side in the vehicle longitudinal direction. A rear portion (152a) in the vehicle longitudinal direction at the upper edge portion (52a) is formed at a position at which, when the webbing (24) is twisted, the rear portion (152a) abuts a twisted portion of the webbing and correction of the twisted portion is possible.

  • Patent number: 5875588
    Abstract: A position detecting device of a moving body can detect the position of a window glass of a power window device with high precision, and can set an initial position of the window glass without making any complicated adjustment. Further, this device can be realized with a simple structure and at low cost. Furthermore, the position detecting device and the vehicle door can reliably maintain an original assembly function in a normal assembly state into the moving body. The position detecting device 30 has a pushing button 202. Rotation of a ring gear 46 can be compulsorily prevented by pushing the pushing button 202 even in an operating state of a motor. Thus, if the motor is driven by pushing the pushing button 202, the position detecting device can be reliably assembled into a vehicle body in the normal assembly state irrespective of a rotating position of a motor rotating shaft (e.g.
