Abstract
A partitioned impact absorber comprising an array of partitions extending parallel to a given impact direction. The absorber is constituted by at least two mutually-engageable blocks, each block having partitions, the partitions of each block interfitting between the partitions of the other block so as to build up the array of partitions of the absorber.
Claims13
A partitioned impact absorber comprising an array of partitions extending parallel to a given impact direction, the absorber being constituted by at least two mutually-engageable blocks, each block having partitions connected together, said partitions defining cells, each cell being delimited by a couple of pairs of walls, the partitions of each block interfitting between the partitions of the other block so as to build up the array of partitions of the absorber.
A bumper beam including a first block of a partitioned impact absorber, wherein:
- said impact absorber comprises an array of partitions extending parallel to a given impact direction, the absorber being constituted by said first block and at least a second block, said first and second blocks being mutually-engageable, each block having partitions connected together, said partitions defining cells, each cell being delimited by a couple of pairs of walls, the partitions of each block interfitting between the partitions of the other block so as to build up the array of partitions of the absorber,
- said first block is constituted by a portion of said bumper beam.
A partitioned impact absorber comprising an array of partitions extending parallel to a given impact direction, the absorber being constituted by at least two mutually-engageable blocks, each block having partitions, the partitions of each block interfitting between the partitions of the other block so as to build up the array of partitions of the absorber, wherein the thickness of the partitions of each block tapers towards the other block.
A partitioned impact absorber comprising an array of partitions extending parallel to a given impact direction, the absorber being constituted by at least two mutually-engageable blocks, each block having partitions, the partitions of each block interfitting between the partitions of the other block so as to build up the array of partitions of the absorber, wherein said absorber includes:
- a first block having a first set of partitions;
- a second block having a first side carrying a second set of partitions suitable for interfitting with the first set of partitions by the first block being engaged in the first side of the second block, and a second side opposite from its first side and carrying a third set of partitions;
- and
- a third block having a fourth set of partitions suitable for interfitting with the third set of partitions by the third block engaging in the second side of the second block.
A partitioned impact absorber comprising an array of partitions extending parallel to a given impact direction, the absorber being constituted by at least two mutually-engageable blocks, each block having partitions, the partitions of each block interfitting between the partitions of the other block so as to build up the array of partitions of the absorber, wherein partitions of each block define cruciform cross-sections.
A partitioned impact absorber comprising an array of partitions extending parallel to a given impact direction, the absorber being constituted by at least two mutually-engageable blocks, each block having partitions, the partitions of each block interfitting between the partitions of the other block so as to build up the array of partitions of the absorber, wherein each block has four walls which are connected together to define a rectangle parallelepiped-shaped volume, said volume containing partitions of the same block.
