An impact absorbing member is disposed between a roof panel and a top ceiling disposed below the roof panel. The impact absorbing member includes a base plate portion and a hollow, cone-shaped portion extending upward from the base plate portion. The cone-shaped portion has a fragile portion that facilitates vertical crush and deformation.

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.

A vehicle trim panel assembly includes a pillar trim panel, a grab handle extending from the pillar trim panel defining a corner between the pillar trim panel and the grab handle, and a ramp at the corner. The ramp is fixed relative to the pillar trim panel and the grab handle at the corner. The ramp is deformable relative to the grab handle.

An embodiment vehicle panel assembly includes an inner panel configured to wrap a roof and opposite pillars of a vehicle body, the inner panel including a second inner assembly portion provided at pillar-side opposite side parts and a guide portion provided at an upper side of the second inner assembly portion, and an outer panel configured to be loaded from above the inner panel and coupled to the inner panel to wrap an outside of the inner panel, the outer panel including a second outer assembly portion provided at a side part, the second outer assembly portion configured to be guided downwards by the guide portion when loaded from above and facing the second inner assembly portion after loading, wherein the second outer assembly portion is fastened to the second inner assembly portion.

A vehicle trim panel assembly includes a pillar trim panel, a grab handle extending from the pillar trim panel defining a corner between the pillar trim panel and the grab handle, and a ramp at the corner. The ramp is fixed relative to the pillar trim panel and the grab handle at the corner. The ramp is deformable relative to the grab handle.

A vehicle pillar structure is provided including a pillar frame that configures framework of a pillar and that includes a flange portion configuring an attachment counterpart for a weather strip at a vehicle front-rear direction rear end portion of the pillar frame, a garnish that is attached to a vehicle width direction inner side of the pillar frame and that configures a styling face of a vehicle cabin interior, and plural ribs that are integrally formed to a face of the garnish on the pillar frame side, that are supported by the flange portion through the weather strip, and that are arrayed in a pillar length direction.

A vehicle includes a vehicle body including a pillar. The pillar includes a support structure. A passenger compartment is defined by the vehicle body. A trim member disposed in the passenger compartment on the pillar. An energy absorption member is coupled to the trim member. The energy absorption member includes a base and at least one rib extending from the base.
