Abstract: A seat cushion for a vehicle seat having attachment members for selectively attaching a child seat thereto includes a first layer having a first hardness and a second layer having a second hardness. The second layer is less hard than the first layer and defines a support surface upon which the child seat sets.

Abstract: The present invention relates to an environmentally friendly layered vehicle seat assembly and a method of making the same. In at least one embodiment, the vehicle seat assembly comprises a cushion composite comprising a structural layer and a cushion layer adjacent to the structural layer, and a trim material secured over the cushion composite.

Abstract: Vibration dummy apparatus adapted to sit on and be supported by a vehicle seat to accurately simulate human vibration response at an interface between the apparatus and seat cushions of the vehicle seat is disclosed. The apparatus includes a relatively hard and stiff skeletal frame structure having a pelvic girdle, a pair of femurs, and a pair of ball-and-socket joints for connecting their respective femurs to the pelvic girdle. Elastomeric plastic is formed over the skeletal frame structure. The elastomeric plastic has a substantially anatomically-correct, surface geometry. The elastomeric plastic formed over the pelvic girdle and the pair of femurs has mechanical properties including human-like, soft tissue spring and damping characteristics. A mass-spring system is connected to the pelvic girdle to at least partially simulate vibration response of an upper section of a human.

Abstract: A biofidelic human seating surrogate apparatus adapted to sit on and be supported by a vehicle seat to simulate human loading of the vehicle seat is disclosed. The apparatus includes a substantially geometrically-correct, relatively hard and relatively stiff skeletal frame structure having a substantially correct density. The structure, in turn, includes: a thoracic cage, a pair of scapulae connected at opposite sides of the thoracic cage, a set of lumbar vertebrae connected to the thoracic cage, a pelvic girdle connected to the lumbar vertebrae, a coccyx connected to the pelvic girdle, a pair of femurs, and a first pair of ball-and-socket joints for connecting their respective femurs to the pelvic girdle. The structure further includes elastomeric plastic formed over the skeletal frame structure. The elastomeric plastic has a substantially anatomically-correct, surface geometry and a substantially correct density.
