Claims
- 1. A bumper system comprising:
a bumper beam having a face and ends; and an energy absorber mounted on the face, the energy absorber having a foam piece engaging the face and an injection-molded end piece securely attached to an end of the foam piece and also engaging the face.
- 2. The bumper system defined in claim 1, wherein the injection-molded end piece includes attachment flanges that extend into the foam piece and anchor the injection-molded end piece in the foam piece.
- 3. The bumper system defined in claim 1, wherein the injection-molded end piece is insert-molded into the foam piece during the process of molding the foam piece.
- 4. The bumper system defined in claim 1, including a second injection-molded piece securely attached to a second end of the foam piece.
- 5. The bumper system defined in claim 4, wherein the second injection-molded piece comprises a second injection-molded end piece.
- 6. The bumper system defined in claim 5, including a second foam piece and a center-located third injection-molded piece, the first-mentioned and second foam pieces being securely attached to ends of the center-located third injection-molded piece, and the first-mentioned and second end pieces being attached to outer ends of the first-mentioned and second foam pieces, respectively.
- 7. A bumper system comprising:
a bumper beam having a face and ends; and an energy absorber mounted on the face, the energy absorber having at least one foam piece engaging the face and at least one non-foam plastic piece securely attached to an end of the foam piece and also engaging the face, the foam piece and the non-foam piece forming a single member that can be handled and attached as a unit to the bumper beam.
- 8. A method comprising steps of:
molding a non-foam plastic component; molding a foam component; attaching the non-foam plastic component to the foam component to form a unitary member that can be handled as a unit; and engaging the unitary member against a face of a bumper beam.
- 9. A bumper system comprising:
a bumper beam having a face surface; and an energy absorber engaging the face surface, the energy absorber having an elongated non-foam injection-molded component with at least three longitudinally-spaced enlarged sections and a plurality of foam sections attached to the molded components between the enlarged sections.
- 10. The bumper system defined in claim 9, wherein the foam sections each fill a space defined between the adjacent enlarged sections on sides of the space.
- 11. The bumper system defined in claim 9, wherein the enlarged sections are each box-shaped and have a hollow interior space.
- 12. The bumper system defined in claim 11, wherein the enlarged sections each include a front wall with marginal material forming an opening therein.
- 13. The bumper system defined in claim 12, including a crush tower tube that extends from the marginal material rearwardly toward the bumper beam.
- 14. The bumper system defined in claim 9, wherein the injection-molded component is one-piece and the enlarged sections are interconnected by connecting straps.
- 15. The bumper system defined in claim 9, wherein the injection-molded component includes end piece sections and wherein the enlarged sections include at least one centered box-shaped section.
- 16. The bumper system defined in claim 9, wherein a front surface of the energy absorber includes first areas defined by the injection-molded component, and further includes second areas defined by the foamed sections.
- 17. The bumper system defined in claim 9, wherein the molded component includes end sections each having a pocket shaped to receive an end of the bumper beam.
