FIELD: motor car construction.
SUBSTANCE: plastic protective plate comprises strip of stiff plastic and strip of soft plastic. Said strips contact in definite zones. Every zone wherein a definite gap exists between said strips to make a cell filled with air. Said cell is confined by tight joint and filled with air. Tight joint is made by welding or gluing to ensure mechanical strength higher than stress originating in the cell at impact. Method of production comprises the steps whereat two strips are moulded. Soft plate is applied on stiff one to make the cell. The cell is filled with air and confined by tight joint. Tight joint is performed by laser welding or gluing. Vehicle includes said protective panel secured at the body part.
EFFECT: higher protective properties of protective panel.
