VEHICLE BUMPER BEAM

摘要

A vehicle bumper beam including: a resin beam having an elongate body extending along a vehicle-width direction, two tubular shock-absorbing portions disposed at the beam body's opposite longitudinal end portions extending in front-rear direction, the beam body and shock-absorbing portions being formed with each other; a metal beam disposed outside the resin beam in the front-rear direction, fixedly fitted to the resin beam. Further, flat attachment portions, formed with inner end portions of the shock-absorbing portions in front-rear direction; bent portions bent in a crank extending from attachment portions outward in front-rear direction, the beam body being to attachment portions via bent portions, the metal beam fixedly fitted to an outer surface of the beam body's intermediate portion; metal beam's opposite end portions extending beyond bent portions covering the right and left sides, fixedly fitted to distal end portions; each space defined by shock-absorbing portion, metal beam and bent portion.

主权项

1. A vehicle bumper beam of a hybrid type including:
a resin beam having an elongate beam body disposed so as to extend along a vehicle-width direction, and a pair of tubular shock absorbing portions respectively disposed at opposite longitudinal end portions of the beam body so as to extend in a vehicle front-rear direction, the beam body and the shock absorbing portions being formed integrally with each other; and a metal beam disposed on an outside of the resin beam in the vehicle front-rear direction and fixedly fitted to the resin beam, the vehicle bumper beam further comprising flat attachment portions to be attached to a vehicle body, and bent portions bent in a form of a crank so as to extend from the attachment portions outward in the vehicle front-rear direction, the flat attachment portions being formed integrally with inner end portions of the shock absorbing portions in the vehicle front-rear direction, the beam body being integrally coupled to the attachment portions via the bent portions, the metal beam being placed on and fixedly fitted to an outer surface of an intermediate portion of the beam body so as to be in contact with the outer surface, and opposite end portions of the metal beam extending beyond the bent portions so as to cover the shock absorbing portions on right and left sides, and are fixedly fitted to distal end portions of the shock absorbing portions, and each space being defined by the shock absorbing portion, the metal beam and the bent portion.
