  • Patent number: 9156505
    Abstract: An upper end joint portion which has increased rigidity by being bent in a rectangular wave shape and is joined to a roof side rail reinforcement is formed at an upper end portion of a center pillar reinforcement. Then, in the roof side rail reinforcement, longitudinal beads and extending in a direction orthogonal to a vehicle front-back direction are formed further on only the rear side in the vehicle front-back direction than a front-side end edge in the vehicle front-back direction in the upper end joint portion in the upper side in a vehicle up-and-down direction of a joint portion to the center pillar reinforcement.

  • Patent number: 8911004
    Abstract: A vehicular center pillar with improved proof stress against loads input from above a vehicle includes a pillar body that extends in a vertical direction of the vehicle and has flanges, formed on the front and rear sides of the pillar body, that extend in a longitudinal direction of the vehicle, and a reinforcing member that connects the front flange to the rear flange. The reinforcing member includes a predetermined connection portion that rectilinearly connects the front flange to the rear flange in the longitudinal direction.

  • Patent number: 8690230
    Abstract: A body front structure of a vehicle includes: a first connecting member that extends in a vehicle width direction, is open upward in a side sectional view, and connects a front end portion and a rear end portion of a cowl together; and a second connecting member that extends in the vehicle longitudinal direction, in a position to a rear of the cowl in the vehicle longitudinal direction and to an inside of a front pillar inner panel in the vehicle width direction, a front end portion of the second connecting member being fixed to the rear end portion of the cowl so as to overlap with the first connecting member when viewed along the vehicle longitudinal direction, and a rear end portion of the second connecting member being fixed, together with a bracket joined to an instrument panel reinforcement, to the front pillar inner panel.

  • Publication number: 20130020833
    Abstract: A vehicular center pillar with improved proof stress against loads input from above a vehicle includes a pillar body that extends in a vertical direction of the vehicle and has flanges, formed on the front and rear sides of the pillar body, that extend in a longitudinal direction of the vehicle, and a reinforcing member that connects the front flange to the rear flange. The reinforcing member includes a predetermined connection portion that rectilinearly connects the front flange to the rear flange in the longitudinal direction.

  • Patent number: 7884704
    Abstract: A body structure of a vehicle reliably detects, with a side-collision detection sensor disposed on a pillar, a side-collision of a side door of a vehicle body against a pole and particularly a side-collision against a pole in a diagonal direction. A metal bracket that projects toward a vehicle width direction outer side is disposed on an outer side surface in a predetermined position (substantially intermediate position between a front pillar and a center pillar) of a rocker. By setting this metal bracket on the outer side of the rocker, in addition to an impact beam disposed inside a door, an acceleration (sensor G) transmitted to the side-collision detection sensor disposed inside the center pillar increases during a side-collision against a pole in a diagonal direction, so the side-collision state can be reliably and rapidly detected even at a position distant from the center pillar.

  • Patent number: 7762620
    Abstract: A vehicle body side structure is provided in which a load transmission member has a lateral inboard portion and a load-receiving member has a lateral outward portion facing the lateral inboard portion of the load transmission member. The lateral inboard portion and the lateral outward portion are configured to transmit loads, applied on a vehicle door in multiple directions from an inner door auxiliary member to a crossmember. Accordingly, the load applied to a location offset from the load transmission member and the load applied on the vehicle door in the direction oblique to the lateral direction of the vehicle are effectively transmitted to the crossmember (vehicle body) without substantial reduction of the road transmission rate. Thus, transferring the force of an offset impact as efficiently as that of an impact that occurs on the location of the load transmission member.

  • Patent number: 5884734
    Abstract: An air damper includes: a piston adapted to reciprocate in a cylinder; an annular recessed portion formed along an outer periphery of the piston; a sealing member fitted in the recessed portion in a slidable manner, adapted to slidingly contact an inner peripheral surface of the cylinder, and forming air chambers on both sides of the piston, respectively, together with the piston; a communicating device allowing the air chambers formed on both sides of the piston to communicate with each other or not to communicate with each other depending on a stopping position of the sealing member; and a reduced-diameter portion formed by reducing a diameter of the cylinder on one end side thereof so as to gradually increase a frictional force between an inner periphery of the reduced-diameter portion and the sealing member.
