Abstract
A vehicle seat includes a generally horizontal sitting portion connected to a generally vertical backrest, and an armrest connected to the sitting portion or the armrest. At least one of the sitting portion, the backrest, or the armrest includes a plastically deformable cellular structural material arranged therein. Another embodiment is an armrest for a vehicle seat including an elastically deformable cushion material and a plastically deformable cellular structural material. A further embodiment is a vehicle seat including a sitting portion connected to a backrest, and an armrest connected to at least one of the sitting portion and the backrest. The armrest includes an elastically deformable cushion material and a plastically deformable cellular structural material. A variation of the armrest includes a barrier interposed between the cushion material and the cellular structural material. The sitting portion and the backrest each include plastically deformable cellular structural material arranged therein. For each embodiment, the cellular structural material includes at least one hollow cell having walls disposed normal to the direction a side impact force acts during a collision…
