Abstract

To reinforce a bumper in order to restrain flexural deformation of a bumper fascia. A garnish 13 has a horizontal part 130 arranged along an upper edge of a front bumper fascia 2, right and left side leg parts 131R, 131L, and a central leg part 132. A bottom end of the side leg part 131 extends to a position for engaging with a projection bar 2b formed on a back face of the front bumper fascia 2 and extending in a vehicle width direction. A bottom end of the central leg part 132 is locked with a projection part 2a with high rigidity constituting a seat to be fastened with a front cross member 22. The side leg part 131 also has a wind-guide plate part 134 spreading backward of a vehicle body, and traveling winds are introduced into a radiator by the wind-guide plate part 134. The garnish 13 and the front bumper fascia 2 are injection-molded using one molding die.

Description

technical field [0001] The invention relates to a bumper structure for automobiles, in particular to a bumper fascia made of plastic materials. Background technique [0002] A bumper made of a plastic material is fixed to, for example, a shroud as a vehicle body front structure and a front frame using fasteners such as bolts, as disclosed in Japanese Patent Application Laid-Open No. 2002-59794 The cross member and the like are thus fixed to the vehicle body. In addition, as disclosed in the patent documents Japanese Patent Laid-Open No. 2002-59794 and Japanese Patent Laid-Open No. 10-6891, components such as radiator grilles are installed on the bumper. The grille and bumper are attached to the bumper by combining claws and hooks integrally formed with the bumper and openings for receiving them. [0003] However, when the thickness of the bumper is reduced to reduce the weight of the automobile, the thickness of the bumper can be bent and deformed with the thinning, for ex...
