  • Publication number: 20210277933
    Abstract: A drive shaft includes a first annular wall and a second annular wall joined together via a friction-welded portion. The first annular wall and the second annular wall have outer diameters of 30 to 50 mm and wall thicknesses of 3 to 5 mm. A burr created at the friction-welded portion has a connection radius of greater than or equal to 0.5 mm, a base radius of greater than or equal to 0.5 mm, a burr base angle of less than or equal to 40°, and a burr slope length of 0.2 to 5 mm.

  • Patent number: 7731281
    Abstract: An impact absorbing plate 31 is disposed between a front part 31z of the impact absorbing plate 31 and a vehicle body 11 so that a rupture generating part 44 ruptured by impact is extended in the front and rear direction of the vehicle, and the impact absorbing plate 31 is fixed to a front part 13a and a rear part 13b of the front seat bracket 13 provided in the vehicle body by rivets 33 and 33. A portion of front part 31z of the impact absorbing plate 31 is cut to form a cutoff part 45, and a front end 17a of a rail 17 provided in a seat section is attached to a convex part 35, which is molded so as to expand upward an inner side of the cutoff part 45, by a rivet 34.

  • Publication number: 20080315635
    Abstract: A rear end collision shock absorbing unit wherein there are provided one-side member rotating in synchronization with either one side of the seat back side and the seat cushion side between members that turn mutually to enable tilting, and the other-side member rotating in synchronization with the other side, and a convex part is provided on the one-side member, a concave part or a through hole in which the convex part fits is provided in the other-side member, and when a rear end collision shock is applied, the convex part and the concave part or through hole are turned relatively and deformed in a fitted state, whereby rear end collision shock energy is absorbed.
