Abstract

There is provided a head-rest of a car sheet which is configured to includes: a skin configured to cover a surface of the head-rest; a foamed material filled in the head-rest covered by the skin; and a stay extending to an outside from the skin in which the foamed material is filled, wherein the head-rest has a gate shape by indenting a center portion of a lower surface of the head-rest, and a groove portion is formed at the indented center portion of the gate shape by making end portions of the skin abut against each other, and members which are softer than the skin are seamed to the respective end portions of the skin which abut against each other in the groove portion.

First claim

The invention claimed is:

1. A head-rest of a car seat mounted on a car seat, comprising:
a skin configured to cover a front surface of the head-rest;
a foamed material filled in the head-rest covered by the skin; and
a stay extending from the skin in which the foamed material is filled to an outside,
wherein the head-rest has a gate shape by indenting a center portion of a lower surface of the head-rest,
a groove portion is formed at the indented center portion of the gate shape by making end portions of the skin abut against each other, and
members which are softer than the skin are seamed to the respective end portions of the skin which are made to abut against each other and the members are inside a bag-shaped space formed by the skin at the groove portion.

2. The head-rest of a car seat according to claim 1 , wherein the members which are softer than the skin and are seamed to the respective end portions of the skin are seamed with each other.

3. The head-rest of a car seat according to claim 2 , wherein the skin is formed in a closed bag shape by seaming a plurality of skin members and the soft members together.

4. The head-rest of a car seat according to claim 2 , wherein the skin is formed by making a plurality of members overlap with each other, and the members which are seamed to the respective end portions of the skin and are softer than the skin are formed of the same member as some of the plurality of members for forming the skin.

5. The head-rest of a car seat according to claim 2 , wherein the members which are seamed to the respective end portions of the skin and are softer than the skin are formed of a member different from the members for forming the skin.

6. The head-rest of a car seat according to claim 2 , wherein a hole through which a material for forming a foamed material is filled into the head-rest covered by the skin is formed in the skin at the center portion in the vicinity of the groove portion.

7. The head-rest of a car seat according to claim 1 , wherein the members which are softer than the skin and are seamed to the respective end portions of the skin are adhered to each other.

8. The head-rest of a car seat according to claim 7 , wherein a hole through which a material for forming a foamed material is filled into the head-rest covered by the skin is formed in the skin at the center portion in the vicinity of the groove portion.

9. The head-rest of a car seat according to claim 1 , wherein the skin is formed in a closed bag shape by seaming a plurality of skin members and the soft members together.

10. The head-rest of a car seat according to claim 1 , wherein the skin is formed by making a plurality of members overlap with each other, and the members which are seamed to the respective end portions of the skin and are softer than the skin are formed of the same member as some of the plurality of members for forming the skin.

11. The head-rest of a car seat according to claim 1 , wherein the members which are seamed to the respective end portions of the skin and are softer than the skin are formed of a member different from the members for forming the skin.

12. The head-rest of a car seat according to claim 1 , wherein a hole through which a material for forming a foamed material is filled into the head-rest covered by the skin is formed in the skin at the center portion in the vicinity of the groove portion.

13. A head-rest of a car seat mounted on a car seat,
wherein a surface of the head-rest is covered by a skin and a foamed material is filled in the head-rest,
the head-rest has a gate shape by indenting a center portion of a lower surface of the head-rest,
a groove portion is formed at the center portion of the gate shape by making end portions of the skin abut against each other, and
in the groove portion, members which are softer than the skin are seamed to the respective end portions of the skin which are made to abut against each other, and the members which are seamed to the respective end portions of the skin and are softer than the skin are seamed to each other.

14. The head-rest of a car seat according to claim 13 , wherein the skin is formed by making a plurality of members overlap with each other, and members which are seamed to the respective end portions of the skin and are softer than the skin are formed of the same member as some of the plurality of members for forming the skin.

15. The head-rest of a car seat according to claim 14 , wherein a hole through which a material for forming a foamed material is filled into the head-rest covered by the skin is formed in the skin at the center portion in the vicinity of the groove portion.

16. The head-rest of a car seat according to claim 13 , wherein the members which are seamed to the respective end portions of the skin and are softer than the skin are formed of a member different from the members for forming the skin.
