Abstract

PURPOSE: Reinforcing structure of a chassis for a door belt line is provided to prevent movement of a channel, and to improve rigidity of the chassis by combining the reinforcing channel in the upper part of the reinforcing chassis with welding. CONSTITUTION: An outer panel(20) is welded into an upper wall of a channel(40), and an inner panel(10) is welded into a lower wall. A reinforcing chassis(30) is welded into the bent part of the inner panel to reinforce the inner panel. A reinforcing channel(50) supports and connects the channel and the reinforcing chassis. The end of the reinforcing channel is welded into the inner wall of the channel, and the other end of the reinforcing channel is welded into the upper bent part of the reinforcing chassis. The L-shaped reinforcing channel is symmetrical to the lower bent part of the reinforcing chassis. Movement of the channel is prevented with connecting the reinforcing channel to the channel and the reinforcing chassis. The rigidity of the reinforcing chassis is improved against external force.
