摘要:
A reinforcement member (32) of an automotive side sill includes a V-shaped cross-sectional portion (46) formed by bending the reinforcement member so as to follow a lower surface (31b) of an upper portion (31a) of an outer panel (31), joining an upper attaching portion (42) functioning as a resulting bent portion to the upper portion (31a) of the outer panel (31) and bending a distal end of the upper attaching portion (42) downwardly.
摘要:
A method for forming a solidified granular material (15), in which granules (16, 17) are charged into a tubular frame member (11) and then heated together with the frame member, to solidify the granules. The granules include a mixture of first granules (16) and second granules (17), each of which second granules has a thermoplastic resin shell enclosing a solid or liquid which expands by vaporization. The mixture is charged into the frame member and heated together with the frame member. The heating causes the second granules (17) to expand and the surfaces of the second granules to melt for bonding with the first granules (16). The mixture, upon cooling, becomes a solidified granular material (15), filling the frame member with no space therebetween.

The high proof bending stress structure member of the present invention includes a thin wall frame structure member, a solidified granular material comprising a first granular material each of which is charged closely inside the thin wall frame structure member, such that one of the first granular material is in contact with another first granular material adjacent thereto, and a thermoplastic resin foam which fills the gap between each of the first granular material and which is welded to the surface of the first granular material whereby connecting the first granular material to each other, and the inner wall of the thin wall frame structure member with the first granular material.
摘要:
A skeleton member structure having a tubular structural member (11, 211) filled with granular materials for absorbing impact energy. The granular materials includes a granular material having a hollow portion (12a, 212a) or a porous granular material. When the skeleton member receives an impact, the granular materials are deformed or collapsed, and impact energy is stably absorbed. Since the granular materials are hollow or porous, the weight of the skeleton member filled with the granular materials is reduced.

摘要:
In a body of a motor vehicle a cross member, provided on a floor panel of the body, elongating widthwise of the motor vehicle is connected to each side sill in a position which is offset from each center pillar. The side sill is provided therein with a reinforcing beam of closed cross section. The reinforcing beam extends in a range at least between a connecting portion of the cross member and a crossing portion of the center pillar and crosses the cross section of the side sill. The reinforcing beam is welded to the side sill over the entire length of the reinforcing beam.
摘要:
A motor vehicle door includes a hollow door body having a pair of vertically spaced hinges mounted on an end thereof. The hinges are mounted on a motor vehicle body for openably closing the door body over a door opening in the motor vehicle body. The motor vehicle door also has a lock mounted on an opposite end of the door body, and a substantially triangular truss fixedly housed in the door body and connected between the hinges and the lock. The substantially triangular truss comprises a vertical beam connected to the hinges and a pair of vertically spaced upper and lower cross beams joined at respective ends thereof to the vertical beam near the hinges, respectively, and joined at respective opposite ends thereof to the lock.
