Joint structure for partial foaming part of instrument panel

摘要

Disclosed herein is a joint structure of a core layer (2) and a skin layer (3) for manufacturing a partial foaming part having a polyurethane foam layer (4) formed between the core layer (2) and the skin layer (3). A recess (21) is formed on the core layer corresponding to the joint of the core layer (2) and the skin layer (3). The recess (21) includes at the inside thereof a guiding wall (22) for the skin layer (3) and a pressing wall (23). A bent portion (31) and a resilient supporting portion (32) are formed in the end portion of the skin layer to be inserted inside the recess (21). The bent portion (31) is bent upwardly so as to contact the guiding wall (22). The resilient supporting portion (32) is resiliently supported underneath the pressing wall (23).
