Abstract
An impact energy absorbing device for a vehicle includes a plurality of cells that are grouped together to form a matrix structure defining a mounting region and a contact region. The cells crush along their respective longitudinal axes when exposed to an impact force on the contact region. Each of the longitudinal axes of the plurality of cells in the matrix structure diverges with respect to neighboring cells in a direction from the mounting region to the contact region.
Claims16
An impact energy absorbing device for a vehicle, the impact energy absorbing device comprising:
- a plurality of cells grouped together to form a matrix structure having a mounting region configured to mount the device to a structural frame of the vehicle, and a contact region configured, in use, to contact a bumper of the vehicle,
- wherein the matrix structure is configured such that each cell crushes along a respective longitudinal axis thereof when exposed to an impact force on the contact region, and
- wherein the longitudinal axes of the plurality of cells in the matrix structure diverge in a direction from the mounting region to the contact region,
- wherein each of the cells tapers outwardly in a direction from the mounting region to the contact region, and
- wherein each cell comprises a mouth portion that is configured to encourage the cell to crush inwardly, towards its center.
