Abstract

A vehicle seat comprises: a pair of opposed frames disposed opposite to and separately from each other; a pair of connecting frames disposed separately from each other in a perpendicular direction perpendicular to an opposing direction of the pair of opposed frames, the connecting frames being configured to connect the pair of opposed frames; a bridging wire disposed to bridge the pair of connecting frames; a reinforcing wire disposed to cross the bridging wire as viewed from an occupant side; and a plate-shaped plastic member configured to cover the bridging wire and the reinforcing wire at least at their crossover such that the bridging wire and the reinforcing wire are arranged to be spaced apart from and thus kept out of contact with each other, the bridging wire and the reinforcing wire being connected with the plate-shaped plastic member.

First claim

What is claimed is:

1. A vehicle seat comprising:
left and right side frames disposed left and right, respectively, opposite to and separately from each other;
front and rear connecting frames disposed in front and in rear, respectively, separately from each other, the connecting frames being configured to connect the left and right side frames; and
a plate-shaped member including:
front and rear hook portions which are hooked on the front and rear connecting frames, respectively;
a base portion disposed between the front and rear hook portions; and
left and right side inclined plates extending from left and right sides of the base portion in obliquely-laterally-outward-and-upward directions,

wherein the base portion includes:
a horizontal portion; and
a front inclined portion extending from a front end of the horizontal portion in an obliquely-frontward-and-upward direction, and

wherein the left and right side inclined plates have laterally inner sides thereof joined respectively to left and right sides of both of the horizontal portion and the front inclined portion of the base portion.

2. The vehicle seat according to claim 1 , wherein upper surfaces of the left and right side inclined plates, an upper surface of the horizontal portion of the base portion, and an upper surface of the front inclined portion of the base portion are formed continuously to one another.

3. The vehicle seat according to claim 1 , wherein the plate-shaped member is of plastic.

4. The vehicle seat according to claim 3 , further comprising a bridging wire disposed to bridge the front and rear connecting frames, the bridging wire including front and rear hooked portions associated respectively with the front and rear hook portions of the plate-shaped member,
wherein the bridging wire is covered and integrally formed with the plate-shaped member.

5. The vehicle seat according to claim 4 , wherein the bridging wire is entirely covered with the plate-shaped member.

6. The vehicle seat according to claim 1 , further comprising a reinforcing wire disposed to cross the bridging wire as viewed from an occupant side,
wherein the reinforcing wire is routed in a region between a first plane and second plane which are perpendicular to a front-rear direction, the first plane containing a front extremity of the left and right side inclined plates and the second plane containing a rear extremity of the left and right side inclined plates.

7. The vehicle seat according to claim 6 , wherein a crossover at which the bridging wire and the reinforcing wire cross is located in the region between the first plane and the second plane.

8. The vehicle seat according to claim 7 , wherein the reinforcing wire includes a front reinforcing wire located in the front inclined portion, and a horizontal reinforcing wire located in the horizontal portion,
wherein both of the front reinforcing wire and the horizontal reinforcing wire are routed in the region between the first plane and the second plane.

9. A vehicle seat comprising:
left and right side frames disposed left and right, respectively, opposite to and separately from each other;
front and rear connecting frames disposed in front and in rear, respectively, separately from each other, the connecting frames being configured to connect the left and right side frames; and
a plate-shaped member disposed between the left and right side frames, the plate-shaped member including:
a base portion located in a laterally central position between the left and right side frames; and
left and right side inclined plates extending from left and right sides of the base portion in obliquely-laterally-outward-and-upward directions,

wherein the base portion includes:
a horizontal portion; and
a front inclined portion extending from a front end of the horizontal portion in an obliquely-frontward-and-upward direction, and

wherein the left and right side inclined plates have laterally inner sides thereof joined respectively to left and right sides of both of the horizontal portion and the front inclined portion of the base portion.

10. The vehicle seat according to claim 9 , wherein upper surfaces of the left and right side inclined plates, an upper surface of the horizontal portion of the base portion, and an upper surface of the front inclined portion of the base portion are formed continuously to one another.

11. The vehicle seat according to claim 9 , wherein the plate-shaped member is of plastic.

12. The vehicle seat according to claim 11 , further comprising a bridging wire disposed to bridge the front and rear connecting frames,
wherein the bridging wire is covered and integrally formed with the plate-shaped member.

13. The vehicle seat according to claim 12 , wherein the bridging wire is entirely covered with the plate-shaped member.
