  • Patent number: 7651135
    Abstract: A lap-belt pre-tensioner operative to draw in a lap belt is disposed on an upper face of a projecting portion so as to extend in a longitudinal direction of a vehicle from an disposition portion of a lower support member, and on the upper face of the projecting portion is provided a groove portion so as to accommodate the lap-belt pre-tensioner in such a manner that the lap-belt pre-tensioner substantially does not project into an ingress-egress opening. Accordingly, there can be provided an occupant protection device of a vehicle equipped with a slide door in which the lap-belt pre-tensioner does not project into the ingress-egress opening.

  • Publication number: 20090184501
    Abstract: A side impact absorbing structure for a vehicle is provided. The structure includes an impact absorbing member which is accommodated in a car body side wall at a position corresponding to a seating region set on a seat, and a buffer unit which is accommodated in the car body side wall and cooperates with the impact absorbing member upon lateral collision to moderate an impact on a side portion of a passenger. The buffer unit includes a rigid body portion which is arranged at a position where the rigid body portion does not overlap the impact absorbing member in the car body side wall and the seating region when seen from the side of a car body.

  • Patent number: 7393047
    Abstract: Disclosed is an automobile roof structure, which comprises a pair of right and left roof side rails 1, a transparent roof panel 4 attached to cover a space between the roof side rails 1, a sun shade 5 disposed slidably along a bottom surface of the transparent roof panel 4, and a shade support member 6 for supporting the sun shade 5 in a slidingly movable manner. Each of the roof side rails 1 includes a rail outer panel 7 and a rail inner panel 8 formed, respectively, with roof flanges 14, 15 which are oriented to protrude in a laterally inward direction of an automobile body and joined together. The roof flanges 14, 15, a lateral peripheral portion of the transparent roof panel 4, and the shade support member 6, are disposed within a given positioning zone where they overlap each other in top plan view.

  • Patent number: 7328918
    Abstract: A seat belt device for a central portion of a rearmost row seat includes a retractor. The retractor is attached at a vehicle roof above a central passenger on the central seat portion of the rear row seat. More specifically, a pair of left and right roof rails are interconnected by a first reinforcement extending in a vehicle width direction before the central passenger, and the first reinforcement and a rear header are interconnected by a second reinforcement extending in a longitudinal direction. A retractor is attached at the first reinforcement. A seat belt withdrawn from the retractor is disposed so as to extend via a seat belt anchor disposed in the rear header.

  • Publication number: 20060290167
    Abstract: A structure of an armrest protruding and extending toward a passenger from an inside wall of a vehicle compartment, comprises a trim body portion covering the inside wall, an armrest face portion extending in a substantially horizontal direction from the trim body portion toward an inside, and a support face portion extending continuously from the armrest face portion downward. There is provided a weak portion (deformation promoting portion) between the trim body portion and the armrest face portion to promote deformation with respect to a lateral load. Further, there is provided a garnish covering the weak portion from the vehicle compartment. Accordingly, both sufficient resistance of the armrest in use for the load applied in the vertical direction and proper impact-absorption function of the armrest during the vehicle side collision can be obtained.

  • Patent number: 5203600
    Abstract: An automotive vehicle has a rear header disposed at a rear end of the roof and above a rear seat. For example, in the event where the automotive vehicle is about to roll, the seat back of the rear seat is leaned forwards and the upper end portion of the seat back is leaned forwards, thereby forcibly repositioning the head of the rear passenger seated on the rear seat to the position remoter from the back window panel.
