A car seat is provided with upholstery with liquid-filled chambers in which the liquid also has elastic bodies. The chambers are connected to one another through passages, so that a liquid exchange can take place among the individual chambers. The damping and resilience properties of the upholstery can be influenced by liquids of different viscosity and/or passages of different shape and size. The upholstery can be used over the full surface of a car seat or selectively in certain areas thereof.

A padding element suitable for use in a crash helmet having a plurality of padding elements including a plurality of first deformable blisters interconnected together in sets, and containing a fluid which is in a saturated vapor state when the helmet has been worn for a sufficient time to raise its fluid temperature to a temperature approaching normal body temperature. It is contemplated that the fluid contained in the first deformable blisters preferably includes a mixture of Freon MF and Freon...

A padding is disclosed for an orthopedic support device including a resiliently deformable foamed plastic layer and a fabric layer laminated to at least one surface of the foam layer to provide an inner surface of the padding for placement against a body member. A plurality of dimples are provided in the inner surface to form air spaces adjacent the body member. Openings are provided in the dimples which extend through the thickness of the foam layer and the fabric to provide airflow between the...

An apparatus for applying an adhesive padding to a tack strip substrate composed of the following elements: (a) a conveyor for conveying a substrate along an elongated path; (b) an arm disposed above the conveyor, pivotable about an axis, biased to a first position, disposed so that the arm comes in contact with the substrate as the substrate is being conveyed along the elongated path by the conveyor, and adapted to be moved from a first position to a second position when brought in contact with...

A pipeline padding vehicle for supplying earth of a fine consistency to cover and pad a pipeline disposed in a trench has a longitudinal conveyor, a vibrating screen to receive earth from the conveyor, and a padding material discharge conveyor beneath the screen to receive material therefrom mounted to pivot about a vertical axis from a position in which it is longitudinally aligned with the vehicle frame to a position transverse of the frame. A sub-frame mounts the vibrating screen and discharg...

The following invention describes padding for a long spinal board. The padding consists of a polyurethane or polyvinyl chloride foam core that has a waterproof covering. The shape of the pad allows it to fit onto any adult size long spinal board currently on the market. Additional padding at one end of the board elevates the head of the patient to an anatomically neutral position. Slots within the padding running longitudinally and transversely permit straps to slide freely inside the padding. T...

A padding press is disclosed for firmly holding sheets of paper to which adhesive, gummed cloth, or other material is to be attached at one edge to make the sheets into pads or books.
