A bumper (1) comprises a body (10) which is connected to a supporting element (20a) oriented in longitudinal direction of the bumper. The supporting element (20a) is provided with one or more connecting means (21) for the attachment of the bumper to a vehicle. The body (10) is constituted of a blow moulded body of thermoplastic material which extends along the bumper from its one end to its other end. The blow moulded body includes at least one cavity (11) whose boundary wall (14a) is connected by fixing means (24) to the supporting element (20a) for the attachment of the body (10) to the same. A method for the manufacture of the bumper is also disclosed wherein the supporting element (20a) is introduced into a blow mould (40) to form a part of the surfaces of the blow mould. A tubular parison of thermoplastic material is expanded against the mould surfaces and the body thus formed attaches to the supporting element by fixing means and/or adhesive provided on the supporting element. |
