Abstract

A seat capable of exhibiting improved seating characteristics. A backing cloth member of a one-piece structure is stretchedly arranged form a seat back section of a seat frame to a seat cushion section thereof. A net-skin member of a one-piece structure is laminated on a front surface of the backing cloth member so as to extend from the seat back section to the seat cushion section. The net-skin member includes a front mesh layer, a rear mesh member and a number of piles arranged between the front mesh layer and the rear mesh layer to connect the front and rear mesh layers to each other therethrough. Such constriction permits a central region of the net-skin member which exhibits maximum cushion characteristics to be arranged at a position corresponding to the hip to waist of a person on the seat, to thereby eliminate a hard feeling of the frame member positioned at an interface between the seat back section and seat cushion section, resulting in seating characteristics of the seat being highly improved.

Claims

1. A seat comprising:

a seat frame including a seat back section and a seat cushion section;

a backing cloth member constructed into a one-piece structure and strechedly arranged from said sat back section to said seat cushion section; and

a net skin member of a one-piece structure including a front mesh layer, a rear mesh member and a number of piles arranged between said front mesh layer and said rear mesh layer to connect said front and rear mesh layers to each other therethrough and layered on a front surface of said backing cloth member so as to extend from said seat back section to said seat cushion section;

wherein said backing cloth member includes a laterally extending slit therein, said slit being arranged at a position corresponding to said seat back section of said seat frame.

2. A seat as defined in claim 1, wherein said backing cloth member is so constructed that a height thereof positionally corresponding to a central region of said seat back section defined in a width direction thereof is set so as to positionally correspond to the thoracic vertebrae of a person on said seat.

3. A seat as defined in claim 1, wherein said piles are formed by knitting a single thread between said front mesh layer and said rear mesh layer.
