Vehicle seat cushion

Claim 2

A vehicle seat cushion including a frame having an outer peripheral portion, a cushioning material disposed over said frame and a surface material covering throughout said cushioning material with each end portion of said surface material being fixed to said frame, wherein at each end portion of said surface material there is provided a connection piece with a cover portion, said connection piece at a position opposed to the outer periphery of said frame with said connection piece connected to the outer peripheral portion of said frame, and said cover portion of said surface material extended to a position lower than said connection piece to form a depending cover surface for covering and concealing the connection of said connection piece to said frame; said outer peripheral portion of said frame being bent downwards to form a bent piece, a tubular turnup portion at the lower end of said bent piece, holes in the upper side of said turnup portion, ring-like clips adapted to surround said turnup portion pass through said holes, and means associated with said frame for securing said connection piece at opposite ends of said frame with said ring-like clips being hidden from view by said turnup portion.

Claim 3

The vehicle seat cushion as set forth in claim 1, wherein said connection piece is formed integrally with said surface material.

Claim 4

The vehicle seat cushion as set forth in claim 1, wherein said cover surface projects downwardly from the lower surface of said seat cushion.

Claim 5

The vehicle seat cushion as set forth in claim 1, wherein said end portion of said surface material is formed from three folds, two of said folds forming outer folds and being turned upwardly, and a third of said folds forming an intermediate fold between said outer folds and being turned downwardly, and means joining said three folds together with a base of said intermediate fold being joined to said outer folds.

Claim 6

The vehicle seat cushion as claimed in claim 4, wherein said means joining said three folds together joins said folds to said end portion of said surface material.

Claim 7

The vehicle seat cushion as claimed in claim 4, wherein said joining means fixes said intermediate fold and a tip end portion to a downwardly extending portion of said surface material connected with one of said outer folds.

Claim 8

A vehicle seat cushion as claimed in claim 1, further including upper rails fixed to the bottom of said frame, said upper rails being slidably mounted on the floor of said vehicle; the pressure of said upper rails not being exerted on said end portion of said surface material since said end portion is not positioned between said upper rails and said frame, thereby preventing damage in use to said end portion.

Claim 9

In combination in a vehicle seat cushion, including a frame having an outer peripheral portion; a cushioning material disposed over said frame and a surface material covering said cushioning material with each portion of said surface material being fixed to said frame; wherein each end portion of said surface material has a connection piece with a cover portion; said connection piece being at a position opposed to the outer periphery of said frame with said connection piece connected to the outer peripheral portion of said frame; said cover portion of said surface material extended to a position lower than said connection piece to form a depending cover surface for covering and concealing the connection of said connection piece to said frame; said outer peripheral portion of said frame being bent downwards to form a bent piece; a tubular turnup portion at the lower end of said bent piece; holes in the upper side of said turnup portion; ring-like clips adapted to surround said turnup portion pass through said holes and securing said connection piece at opposite ends of said frames; and upper rails fixed to the bottom of said frame; said upper rails being slidably mounted on lower rails on the floor of said vehicle; the pressure of said upper rails not being exerted on said end portion of said surface material since said end portion is not positioned between said upper rails and said frame, thereby preventing damage in use to said end portion.

Claim 10

In combination in a vehicle seat cushion, including a frame having an outer peripheral portion; a cushioning material disposed over said frame and a surface material covering said cushioning material with each portion of said surface material being fixed to said frame; wherein each end portion of said surface material has a connection piece with a cover portion; said connection piece being at a position opposed to the outer periphery of said frame with said connection piece connected to the outer peripheral portion of said frame; said cover portion of said surface material extended to a position lower than said connection piece to form a depending cover surface for covering and concealing the connection of said connection piece to said frame; said outer peripheral portion of said frame being bent downwards to form a bent piece; a tubular turnup portion at the lower end of said bent piece; holes in the upper side of said turnup portion; ring-like clips adapted to surround said turnup portion pass through said holes and securing said connection piece at opposite ends of said frames; and upper rails fixed to the bottom of said frame; said upper rails being slidably mounted on lower rails on the floor of said vehicle; the pressure of said upper rails not being exerted on said end portion of said surface material since said end portion is not positioned between said upper rails and said frame, thereby preventing damage in use to said end portion.

Claim 11

The combination of claim 8, wherein: said turnup portion includes three turnups, two of said turnups forming outer portions and a third of said turnups being between said outer turnups; one of said outer turnups being connected with a downwardly extending portion of said surface material; and the other of said outer turnups having a tip end portion, and means connecting said tip end portion with said inner portion to said downwardly extending portion.

Claim 12

The combination of claim 9, including: a bar-like end wire inserted through said third turnup and through said ring-like clips for forming a connection piece proximate to said bent piece for fixing thereto said connection piece, said one of said turnups forming a cover surface for said bent piece to cover the side of said frame and said clips; spring means and connection means for connecting said spring means to said frame above said bent piece for supporting said cushioning material which together with the side walls of said frame and said bent piece are entirely covered with said surface material.
