Reinforced and ventilated seats

A pad for seats, back rests, mattresses and the like comprising a pad body of plastic material, recess means in said pad body, a covering layer overlying said pad body and the recess means therein, strips of reinforcing material sandwiched between said pad body and said covering layer, at least selected ones of said strips being in alignment with said recess means whereby heat is dissipated from the covering layer through said recess means and the pad is reinforced by said strips, said recess means are a plurality of apertures passing through said pad body, said selected ones of said strips overlie said apertures, disc means at the intersection of said strips, and said disc means including projections which project into said apertures.

A pad for seats, back rests, mattresses and the like comprising a pad body of plastic material, recesss means in said pad body, a covering layer overlying said pad body and the recess means therein, strips of reinforcing material sandwiched between said pad body and said covering layer, at least selected ones of said strips being in alignment with said recess means whereby heat is dissipated from the covering layer through said recess means and the pad is reinforced by said strips, said selected strips intersect each other, means connecting said strips to each other at the intersections thereof, and said connecting means being constructed and arranged to permit relative movement between said strips and said connecting means.

A pad for seats, back rests, mattresses and the like comprising a pad body of plastic material, recess means in said pad body, a covering layer overlying said pad body and the recess means therein, strips of reinforcing material sandwiched between said pad body and said covering layer, at least selected ones of said strips being in alignment with said recess means whereby heat is dissipated from the covering layer through said recess means and the pad is reinforced by said strips, said recess means being defined by a plurality of intersecting channels opening upwardly through said pad body, an aperture passing through said pad body at least at selected points of intersection of said channels, and said selected ones of said strips intersecting each other at said points of intersection.

A pad for seats, back rests, mattresses and the like comprising a pad body of plastic material, recess means in said pad body, a covering layer overlying said pad body and the recess means therein, strips of reinforcing material sandwiched between said pad body and said covering layer, at least selected ones of said strips being in alignment with said recess means whereby heat is dissipated from the covering layer through said recess means and the pad is reinforced by said strips, said recess means are defined by a plurality of apertures passing through said pad body, said apertures being overlaid by said strips, and said selected ones of said strips intersecting each other at said apertures.

A pad for seats, back rests, mattresses and the like comprising a pad body of plastic material, recess means in said pad body, a covering layer overlying said pad body and the recess means therein, strips of reinforcing material sandwiched between said pad body and said covering layer, at least selected ones of said strips being in overlying alignment with said recess means whereby heat is dissipated from the covering layer to said recess means and the pad is reinforced by said strips, said recess means are defined by a plurality of apertures passing through said pad body, and said selected ones of said strips being of a width to substantially though not entirely cover said apertures whereby a pumping action is effected during repetitious compression and expansion of said pad body.
