An energy absorbing material includes a multi-cellular structure formed from a plurality of interconnected cells having a lattice structure. Each of the plurality of interconnected cells includes at least four nodes and at least one lattice element extending between each of the at least four nodes. The at least one lattice element has a diameter no greater than 2.5 mm.

A vehicle cushioning member includes first and second bending portions including first and second convex-bending portions, and first and second concave-bending portions. The first and second convex-bending portions and the first and second concave-bending portions are formed perimetrically while switched from each other between the adjacent side walls. When a length from a top surface of the top plate to a flange portion is 100%, a length from the top surface to the first bending portion is 24% or more and 47% or less, a length from the first bending portion to the second bending portion is 34% or more and 49% or less, and a length from the second bending portion to a top-plate-side surface of the flange portion is 13% or more and 33% or less, concerning a height direction along the axis of a substantially polygonal tube.

The shock absorber includes: a base portion fixed to the attachment target; a shock absorbing portion having flexibility and attached to the base portion so as to be reversibly switchable between a housed state in which the shock absorbing portion is retracted toward the base portion and a protruding state in which the shock absorbing portion protrudes from the base portion; and a drive unit driving the shock absorbing portion to reversibly switch between the housed state and the protruding state. The drive unit, when operating the shock absorbing portion, at least switches the shock absorbing portion from the housed state to the protruding state.

An assembly includes a seatback defining an occupant-seating area. The seatback has a frame and a rear trim cover. The frame is between the occupant-seating area and the rear trim cover. The assembly includes a seat bottom extending from the seatback below the occupant-seating area. The assembly includes a deformable cell between the frame and the rear trim cover. The deformable cell extends from a first end proximate the frame to a second end proximate the rear trim cover. The deformable cell has a contraction between the first end and the second end.

There is provided a vehicle crash pad coupled to a passenger airbag door having a passenger airbag installed in a passenger seat direction, the vehicle crash pad including a base forming a frame, a scrim coupled to an inside of the base of the passenger airbag door in an insert-injection method, a skin disposed above the base portion and having a surface exposed to an outside, a foam disposed between the base and the skin, and X shaped incision grooves formed in a rear surface of the base in an area of the passenger airbag door.
