Document Type and Number:
Japanese Patent JPS6294452
Kind Code:
A
Abstract:
A vehicle bumper assembly (10) is provided which comprises a substantially tubular reinforcing beam (14), a face cover (12), and a means for attaching said face cover (12) to said reinforcing beam (14) such that the reinforcing beam (14) includes a material which has a flexural modulus at 72°F, according to ASTM Standard D-790 (0.05 in/min) of about 100,000 psi to about 500,000 psi and a deflection temperature according to ASTM Standard D-698 (264 psi ¼" thick samples) of at least 155°F. The present invention also includes a process for making a vehicle bumper assembly comprising the steps of molding a first material to form a face cover; extrusion molding a second material to form a tubular section; blow molding said tubular section to form a substantially tubular reinforcing beam (14) having means adapted for attaching said reinforcing beam (14) to a vehicle; and attaching said face cover (12) to said reinforcing beam (14).
