Abstract：In view of the deformation and fracture of the folding connecting rod of the third row of a car， this paper analyzes the possible factors of the deformation and fracture of the connecting rod： the production process is wrong， the tool is wrong， the parts are not strong enough， the parts are not designed properly， and the operation method is wrong. Finally， the basic cause of folding link fracture is locked by CAE analysis， and then the corresponding solutions are formulated.

Key words：seat， fold， deformation and fracture
