Abstract

PURPOSE:To easily and positively improve the cushion effect at the time of a car crush, by forming a hollow body of an elastic material such as rubber and filling the inside thereof with air to constitute a bumper. CONSTITUTION:A hollow body for a bumper, which is formed of rubber or an elastic plastic material into a suitable shape, is filled with air through a nozzle 6 to constitute an air-cushion bumper. This bumper may be suitably divided into several pieces and attached to the front side of a metallic bumper 1 or the like already mounted on the autobody. Alternatively, this air-cushion bumper may be mounted alone as a single body. The hollow body 2 is attached to the autobody, for example, by means of a fitting 5 which is engaged with an engaging part 12 formed on the rear face of the hollow member 2. The hollow body 2 is provided on its front side with a groove 3 or a projection so as to further improve the cushion effect thereof.

The IJ shape is applied to the row f'^j to further enhance the cushioning effect.

Of course, even if the shank is not used, it has a perfect cushioning effect because it is made entirely of rubber or plastic and air is press-fitted into its hollow body.

The present invention has been developed to replace the conventional metal bumper with an air cushion bumper.It can be attached to the front of the conventional bumper in the same manner as described above.
