REINFORCING MEMBER FOR INTERFITTING CHANNELS

摘要

A reinforcing assembly (18) for use with roll bars adapted to be mounted to motor vehicles such as an automobile. The reinforcing assembly (18) includes a heat-expandable synthetic resin reinforcing member (40) and a retainer (42) configured to attach the member (40) to the interior of a two-piece telescopically interfitting tubular roll bar construction (12, 14). Upon heating, the reinforcing member expands to form a seal between the two roll bar tube sections (12, 14) thereby providing sound-reduction and stability of the roll bar assembly.
