  • Patent number: 7677643
    Abstract: A body framework construction, includes: a rear seat cross member, extending in a transverse direction of a vehicle, in a rear part of a body in a lower part of a passenger compartment; a dash cross member upper, extending in the transverse direction, in a front part of the passenger compartment; and a backbone, configured into a thin, long shape having a closed cross section, and extending in a longitudinal direction of the vehicle. A front end portion of the backbone is connected to the dash cross member upper via a gusset, and a rear end portion of the backbone is joined to the rear seat cross member. The gusset is deformed more easily than the backbone relative to a force from a front.

  • Patent number: 7614687
    Abstract: An upper member of a pillar has a substantially U-shaped cross section, and includes first side walls extending substantially in a transverse direction of the vehicle at least at a lower portion, and a connecting plate at a lower end while keeping the U-shaped cross section. A lower member includes a mounting plate opposed to the connecting plate at a lower portion being lower than an upper end, and second side walls extending substantially in the transverse direction at both end portions of the mounting plate in a longitudinal direction of the vehicle. The connecting plate and the mounting plate are welded to each other in a state that they are in abutment with each other, and the first side walls and the second side walls are joined to each other, and the upper member and the lower member are integrally fixed to each other.

  • Patent number: 7467816
    Abstract: A door latch device includes a striker, a fork, a pawl lever that locks rotation of the fork, the fork having a first locking part which locks the striker when the fork is shifted from an open state though a half-grasped state to a full-grasped state and a second locking part which is locked with the pawl lever in the half-grasped state, a stopper member which restricts rotation of the pawl lever, and a sound adjusting unit that makes a first striking sound which occurs when the striker strikes the first locking part larger than a third striking sound which occurs when the pawl lever strikes the stopper member is in the full-grasped state of the fork, and that makes a second striking sound which occurs when the pawl lever strikes the second locking part larger than the third striking sound.

  • Publication number: 20080238151
    Abstract: An upper member of a pillar has a substantially U-shaped cross section, and includes first side walls extending substantially in a transverse direction of the vehicle at least at a lower portion. The upper member includes a connecting plate at a lower end while keeping the U-shaped cross section. A lower member includes a mounting plate opposed to the connecting plate at a lower portion being lower than an upper end, and the lower member includes second side walls extending substantially in the transverse direction at both end portions of the mounting plate in a longitudinal direction of the vehicle. The connecting plate and the mounting plate are welded to each other in a state that the connecting plate and the mounting plate are in abutment with each other, and the first side walls and the second side walls or the first and second side walls and wall members attached to the first and second side walls, are joined to each other, and the upper member and the lower member are integrally fixed to each other.

  • Patent number: 7300097
    Abstract: A door for a vehicle includes an outer panel for forming the contour of the door, a door reinforcement formed in a perimeter shape shaped in conformity with the contour of the door, and a substantially U-shaped inner panel that is upwardly open. Front and rear edges and lower edges of the door reinforcement and the inner panel are respectively connected to each other by welding to form a box-shaped section. Both ends of a side impact bar are welded or fused to front and rear vertical walls and of the door reinforcement, and a door hinge is attached to the vertical wall.

  • Patent number: 6932405
    Abstract: A vehicle body structure of the present invention includes a side-frame disposed to extend along one direction, a side sill disposed to extend in the one direction alongside the side-frame on the outside thereof, a cross member disposed to extend in a direction in which the cross member intersects with the side-frame and which is joined to a side portion of the side-frame to form a vehicle body together with the side-frame, and a gusset provided between the side-frame and the side sill on a longitudinal extension of the cross member, which extends in a smaller cross section than that of the cross member from a joint portion where the cross member is joined to the side-frame until the gusset comes into abutment with the side sill while passing through the side-frame and which is formed as an integral part of the cross member.
