Abstract
Official abstract text for this publication.
In a bumper system, one end portion of a first tube is inserted into first beam holes, and the other end portion of the first tube is inserted into a first plate hole, one end portion of a second tube is inserted into second beam holes, and the other end portion of the second tube is inserted into a second plate hole. The bumper stay is joined to a bumper beam and a vehicle body plate by press-fitting in a state in which the first tube is expanded at the holes and the second tube is expanded at the holes. A first connection rib is in contact with the bumper beam, and a second connection rib is in contact with the vehicle body plate in the same direction as a direction in which the first connection rib is in contact with the bumper beam.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bumper system, comprising: a bumper stay in which a first tube and a second tube extending in the same direction are connected by a first connection rib provided at least at one end portion and a second connection rib provided at least at the other end portion; a bumper beam having a first beam hole into which one end portion of the first tube is insertable and a second beam hole into which one end portion of the second tube is insertable; and a vehicle body plate having a first plate hole into which the other end portion of the first tube is insertable and a second plate hole into which the other end portion of the second tube is insertable, wherein: the bumper system is a system in which the bumper stay and the bumper beam are joined and the bumper stay and the vehicle body plate are joined; the one end portion of the first tube is inserted into the first beam hole, the other end portion of the first tube is inserted into the first plate hole, the one end portion of the second tube is inserted into the second beam hole, and the other end portion of the second tube is inserted into the second plate hole; the bumper stay is joined to both the bumper beam and the vehicle body plate by press-fitting in a state in which the first tube is expanded at both the first beam hole and the first plate hole and the second tube is expanded at both the second beam hole and the second plate hole; and the first connection rib is in contact with the bumper beam, and the second connection rib is in contact with the vehicle body plate in the same direction as a direction in which the first connection rib is in contact with the bumper beam in a direction in which the first tube and the second tube extend. 2. The bumper system according to claim 1 , wherein the vehicle body plate includes a plate slit that connects the first plate hole and the second plate hole and is cut out in a shape into which the first connection rib is insertable. 3. The bumper system according to claim 1 , wherein the bumper beam includes a beam slit that connects the first beam hole and the second beam hole and is cut out in a shape into which the second connection rib is insertable. 4. The bumper system according to claim 1 , wherein at least one of the first connection rib and the second connection rib is connected to the first tube and the second tube by welding. 5. The bumper system according to claim 2 , wherein at least one of the first connection rib and the second connection rib is connected to the first tube and the second tube by welding. 6. The bumper system according to claim 3 , wherein at least one of the first connection rib and the second connection rib is connected to the first tube and the second tube by welding.
