Abstract

A vehicular seat provided in a seat surface with a deep and narrow depression having a flat surface at the bottom is provided. The vehicular seat is a seat for automobiles including: a seat cushion to be a seating face portion of the seat; and a seat back provided on the back of the seat cushion and to be a backrest portion of the seat. A recess having a flat surface at the bottom is provided in the surface of at least one of the seat cushion and the seat back.

First claim

The invention claimed is:

1. A vehicular seat comprising:
a seat cushion to be a seating face portion of the seat;
a seat back provided on the back of the seat cushion and to be a backrest portion of the seat;
a seat skin covering a surface of at least one of the seat cushion and the seat back,
wherein a recess having a flat surface comprising a portion of the seat skin at the bottom of the recess is provided in the surface of at least one of the seat cushion and the seat back;
at least first and second supporting members provided substantially in parallel to each other inside the seat cushion or the seat back; and
at least one first drawing member having one end secured to the seat skin and another end secured to the first supporting member, and at least one second drawing member having one end secured to the seat skin and another end secured to the second supporting member,
wherein the flat surface comprising the portion of the seat skin at the bottom of the recess is formed by drawing in the portion of the seat skin to the at least first and second supporting members with the at least one first drawing member and the at least one second drawing member.

2. The vehicular seat according to claim 1 ,
wherein when the seat cushion or the seat back is planarly viewed from the passenger seating face side, the areas where the at least one first drawing member and the at least one second drawing member are secured to the at least one first supporting member and the at least one second supporting member are arranged in a staggered configuration.

3. The vehicular seat according to claim 1 , wherein the depth of the recess is adjusted by varying the length of the at least one first drawing member and the at least one second drawing member and the positions where the at least one first drawing member and the at least one second drawing member and the seat skin and the at least one first supporting member and the at least one second supporting member are fixed together.

4. The vehicular seat according to claim 1 ,
wherein the seat skin is of a three-layered structure at least in an area where the recess is formed.

5. The vehicular seat according to claim 4 ,
wherein the three-layered structure is formed of a combination of a cloth-based jersey material, a urethane material, and a cloth-based tricot material.

6. The vehicular seat according to claim 1 ,
wherein the at least one first supporting member and the at least one second supporting member are metal wires.

7. The vehicular seat according to claim 1 ,
wherein the at least one first drawing member and the at least one second drawing member are made of metal or resin.

8. A method for manufacturing a vehicular seat comprising the steps of:
(a) providing a plurality of drawing members on the underside of a skin material of at least one of a seat cushion and a seat back; and
(b) securing the drawing members on a plurality of supporting members provided substantially in parallel to each other inside the seat cushion or the seat back to form a recess having a flat surface at the bottom on the front side of the skin material.

9. The method for manufacturing a vehicular seat according to claim 8 ,
wherein the drawing members are secured on a plurality of the supporting members such that when the seat cushion or the seat back is planarly viewed from the passenger seating face side, the areas where the drawing members and the supporting members are fixed together are arranged in a staggered configuration.

10. The method for manufacturing a vehicular seat according to claim 8 ,
wherein the depth of the recess is adjusted by varying the length of the drawing members and the positions where the drawing members and the skin material and the supporting members are fixed together.

11. The method for manufacturing a vehicular seat according to claim 8 ,
wherein the skin material is of a three-layered structure at least in an area where the recess is formed.

12. The method for manufacturing a vehicular seat according to claim 11 ,
wherein the three-layered structure is formed of a combination of a cloth-based jersey material, a urethane material, and a cloth-based tricot material.
