Abstract

An easy-to-attach clip member that makes the surroundings of a stay cloth mounting portion compact while maintaining high airbag deployment performance, and an airbag module-equipped seat with the clip member are provided. A clip member is connected to a cloth-form body that transmits a tensile force. The clip member includes a connecting portion connected to one end of the cloth-form body, and a groove engaged with an edge portion of a mounted portion. The clip member is provided to reduce a torque generated at the connecting portion by the tensile force transmitted from the cloth-form body when engaged with the edge portion of the mounted portion, and connects the cloth-form body to the mounted portion.

First claim

The invention claimed is:

1. A mounting member, comprising:
an engagement portion configured to engage with a mounted portion of a side frame of a seat back frame of an airbag module-equipped seat, and
a connecting portion configured to connect to one end of a guide member provided with an edge attached to a tearing portion of a trim cover of the airbag module-equipped seat, where the guide member transmits a tensile force;

wherein:
the mounting member is configured to reduce a torque generated at the connecting portion by the tensile force transmitted from the guide member, when engaged with the mounted portion; and
the mounting member connects the guide member to the mounted portion, when engaged with the mounted portion and connected to the one end of the guide member.

2. The mounting member according to claim 1 , further comprising the tensile force absorbing portion for absorbing the tensile force transmitted from the guide member to reduce the torque.

3. The mounting member according to claim 1 , wherein:
the side frame has a curved flange at an edge portion of the side frame; and
the mounting member further comprises a wide portion formed adjacent to the engagement portion, the wide portion generally conforming to the shape of an area surrounded by the flange and the side frame.

4. The mounting member according to claim 3 , wherein:
a trim plate is fixed to the end portion of the guide member;
an engaging portion for engaging the trim plate is provided at the wide portion; and
the trim plate is configured to be able to be disengaged from the engaging portion by the force of the airbag inflating and deploying.

5. The mounting member according to claim 4 , wherein the engaging portion is a groove provided in the wide portion opposite to the edge portion of the side frame.

6. The mounting member according to claim 4 , wherein at least one of a wall surface forming the engaging portion and one end side of the guide member has a movement restraining portion for positioning the one end side of the guide member with respect to the wall surface in a direction to engage or disengage the one end side of the guide member with or from the engaging portion.

7. The mounting member according to claim 6 , wherein the engaging or disengaging direction is a direction substantially orthogonal to the direction of the tensile force acting on the guide member.

8. The mounting member according to claim 4 , wherein:
a slit is provided in a side wall of the engaging portion, the slit extending to an outside surface of the mounting member;
the slit and the engaging portion are open at at least one of an upper end and a lower end of the mounting member;
a one end side guide portion for guiding insertion of the one end side of the guide member is provided at an open end of the upper end and the lower end of the engaging portion; and
a guide member guide portion for guiding insertion of a portion adjacent to the one end side of the guide member is provided at an end of the upper end and the lower end of the slit at which the one end side guide portion is provided.

9. The mounting member according to claim 8 , wherein:
the one end side guide portion and the guide member guide portion have a chamfered shape formed continuously from the one end side guide portion to the guide member guide portion at an open end of the upper end and the lower end; and
the continuously formed chamfered shape becomes gradually deeper from an end portion of the one end side guide portion toward an end portion of the guide member guide portion.

10. The mounting member according to claim 8 , wherein:
the slit communicates with the engaging portion, and a connection portion between the engaging portion and the slit constitutes a bent passage for the guide member; and
an outside wall of the slit is inclined at an obtuse angle with respect to an outside wall of the engaging portion at a location where the slit is adjacent to the engaging portion.

11. The mounting member according to claim 8 , wherein an edge side of an outside wall of a pair of walls forming the slit, a surface on the slit side of an inside wall of the pair of walls, the engaging portion, a surface on the opposite side to the slit of the engaging portion, the flange, and an engagement area between the mounting member and the flange are located in the same plane.

12. The mounting member according to claim 3 , wherein one of the flange and the wide portion has a protrusion for fixing the flange and the wide portion to each other, and the other has a recess to engage with the protrusion in a position corresponding to the position of the protrusion.

13. The mounting member according to claim 3 , wherein the side frame has a rotation restricting portion to abut the wide portion to restrict the rotation of the mounting member.

14. The mounting member according to claim 13 , wherein:
the engaging portion is held between a pair of walls provided at the wide portion, and has an opening communicating with the outside between the pair of walls;
the rotation restricting portion is a protrusion protruded from the side frame; and
the protrusion is engaged with a distal end portion on the opening side of one of the pair of walls to position the mounting member with respect to the side frame.

15. The mounting member according to claim 1 , wherein the mounting member is integrally molded.

16. The mounting member according to claim 1 , wherein the engagement portion configured to engage with the mounted portion is a groove.

17. A seat equipped with an airbag module housing an airbag, the airbag module-equipped seat comprising:
a side frame extending along a side portion of the seat;
the airbag module mounted to the side frame;
a trim cover for the seat; and
a guide member with an edge attached to a tearing portion of the trim cover, wherein:
a mounting member is connected to the guide member;
the mounting member includes a connecting portion connected to one end of the guide member, and an engagement portion engaged with the side frame;
the mounting member is provided to reduce a torque generated at the connecting portion by a tensile force transmitted from the guide member, when engaged with the side frame; and
the mounting member connects the guide member to the side frame.
