ABSTRACT:
A cross member bumper beam and method of making it are disclosed. The cross member bumper beam is attached to the frame rails of a vehicle. The beam is made of first and second materials that are bonded together with an adhesive. The first step of the method is to form a cross member from the first material. The cross member has a channel shape, with at least one bent return first edge portion. The bent return first edge portion includes a latch portion. The second step of the method is to attach the cross member to the frame rails of the vehicle. The channel shape of the cross member is oriented generally away from the frame rails and exposes the bent first edge portion. The third step of the method is to form a bumper facebar from the second material. The bumper facebar also has a channel shape with at least one bent return second edge portion. The bent return second edge portion includes an attachment portion. The fourth step of the methods is to position the bumper facebar so that the channel shape of the bumper facebar opens in a direction generally opposite to the channel shape of the cross member. The fifth step of the method is to apply the adhesive to at least one of the first and second edge portions. The sixth step of the method is to affix the first and second edge portions for bonding with the adhesive by engaging the attachment portion of the bumper facebar with the latch portion of the cross member.
