Abstract

A vehicle seat includes pad and cover assemblies. The pad assembly has a main portion and side portions. The side portions are placed opposite sides of the main portion through boundary-portion pulling slots respectively. The main-portion pulling slot crossing the boundary-portion pulling slots is formed in the main portion. The cover assembly includes boundary-portion pulling bags pulled into the boundary-portion pulling slots respectively and a main-portion pulling bag pulled into the main-portion pulling slot. The vehicle seat includes boundary-portion insert wires embedded along bottom portions of the boundary-portion pulling slots respectively; boundary-portion end wires inserted into the boundary-portion pulling bags and fixed to the boundary-portion insert wires respectively; and a main-portion end wire inserted into the main-portion pulling bag. The main-portion end wire has opposite end portions bent and is forced into the main-portion pulling slot with the bent opposite end portions linked with the boundary-portion end wires respectively.

Claims

1. A seat comprising:

a pad assembly having a main portion and side portions, the main portion interposed between the side portions, the side portions including boundary-portion pulling slots wherein boundary-portion insert wires having hook ends are disposed along bottom portions of said boundary-portion pulling slots, and the main portion including a main-portion pulling slot disposed substantially perpendicular to the boundary-portion pulling slots;

a cover assembly covering a surface of the pad assembly, the cover assembly including boundary-portion pulling bags pulled into the boundary-portion pulling slots respectively and a main-portion pulling bag pulled into the main-portion pulling slot, wherein boundary-portion end wires having exposed hook ends are inserted into said boundary-portion pulling bags and fixed to said boundary-portion insert wires respectively; and

a main-portion end wire inserted into the main-portion pulling bag, the main-portion end wire having a straight line portion and bent portions positioned at both ends of the straight line portions, and exposed hook portions positioned at both ends of the bent portions, the main-portion end wire being placed into the main-portion pulling slot with the exposed hook ends of said bent opposite end portions linked with the boundary-portion end wires respectively.

2. The seat according to claim 1, wherein each of said boundary-portion end wires inserted into said boundary-portion pulling bags is a single wire.

3. The seat according to claim 1, wherein said main-portion end wire hangs said main-portion pulling bag into said main-portion pulling slot by bending reaction force generated by bending said opposite end portions of said main-portion end wire.

4. The seat according to claim 1, wherein said main-portion end wire is made from an elastic material.

5. The seat according to claim 2, wherein said main-portion end wire is made from an elastic material.

6. The seat according to claim 3, wherein said main-portion end wire is made from an elastic material.

7. The seat according to claim 1, wherein each of said boundary-portion end wires is formed from a single wire, wherein said bent opposite end portions of said main portion end wire are linked with intermediate portions of said boundary-portion end wires respectively.

8. The seat according to claim 1, wherein said boundary-portion insert wires are made from a U-shaped single insert wire.

13. The seat according to claim 1, wherein the main-portion end wire is a single wire.

9. A seat comprising:

a pad assembly having a plurality of pulling slots extending in directions crossing one another; and

a cover assembly having a plurality of pulling bags pulled into said pulling slots correspondingly and respectively so that said cover assembly covers a surface of said pad assembly;

wherein at least one insert wire with hook ends is embedded in bottom portions of said pulling slots except at least one pulling slot, while end wires with exposed hook ends are inserted into all of said pulling bags respectively; and

wherein at least one said end wire includes a main-wire end portion, said main-wire end portion having a straight line portion and bent portions positioned at both ends of the straight line portions, and exposed hook portions positioned at both ends of the bent portions; and

wherein when said bent portions of said main-wire end portion inserted into one of said pulling bags are pulled into said at least one pulling slot, said bent opposite end portions with exposed hook portions are hooked with said end wires of said pulling bags pulled into said pulling slots other than said at least one pulling slot, and when said main-wire end portion with hooked bent opposite end portions is forced into said at least one pulling slot, said pulling bag having said main-wire end portion inserted thereto is pulled into said at least one pulling slot.

10. The seat according to claim 9, wherein said at least one insert wire is formed from a U-shaped single wire.

11. The seat according to claim 9, wherein said at least one insert wire comprises two insert wires.

12. A seat comprising:

a pad assembly having a main portion and side portions, the main portion interposed between the side portions, the side portions including boundary-portion pulling slots wherein boundary-portion insert wires are disposed along bottom portions of said boundary-portion pulling slots, and the main portion including a main-portion pulling slot disposed substantially perpendicular to the boundary-portion pulling slots;

a cover assembly covering a surface of the pad assembly, the cover assembly including boundary-portion pulling bags pulled into the boundary-portion pulling slots respectively and a main-portion pulling bag pulled into the main-portion pulling slot, said boundary-portion pulling bags having cut portions at intermediate portions thereof, wherein boundary-portion end wires are inserted into said boundary-portion pulling bags and fixed to said boundary-portion insert wires respectively, and said boundary-portion end wires being exposed at said cut portions thereof; and

a main-portion end wire inserted into the main-portion pulling bag, the main-portion end wire having opposite end portions bent, the main-portion end wire being placed into the main-portion pulling slot with the bent opposite end portions linked with the boundary-portion end wires respectively.
