Abstract

A front seat belt retractor disposing structure which has a floor cross member formed in a hollow inverted U-shaped cross-section in such a manner that the lower opening makes contact with the floor of a vehicle under a rear seat along the transverse direction for containing a front seat belt retractor so that a front seat belt can be drawn externally. Thus, the front seat belt retractor disposing structure can provide sufficient rear seat passengers'"'"' accommodation and feet retention spaces by containing the retractor within the floor cross member.

Claims

1. A front seat belt retractor disposing structure comprising:

a center floor cross member having at least one opening under a rear seat, through which opening a front seat belt retractor is inserted and is fastened within said floor cross member, said retractor being disposed for a seat belt to be drawn through said opening to the front seat side, and one end of said seat belt being arranged through the center of the front seat.

2. The front seat belt retractor disposing structure according to claim 1, wherein said floor cross member is formed in a hollow inverted U-shaped cross-section in such a manner that the lower opening thereof makes contact with a floor of a vehicle under a rear seat along the traverse direction of the vehicle.

3. The front seat belt retractor disposing structure according to claim 1, wherein an anchoring member of the retractor is fastened to the floor tunnel and the cross member, thereby fastening the retractor into the cross member.

4. The front seat belt retractor disposing structure according to claim 1, wherein said floor cross member includes a sub floor cross member having an inverted U-shaped cross-section, a length corresponding to the width of a vehicle and a rising part formed with a predetermined space defined by the surface of the floor and the side surface of a floor tunnel, said sub floor cross member being coupled with a reinforcing member formed with a hollow inverted U-shaped cross-section, said reinforcing member having the same shape as the predetermined space of said sub floor cross member.

5. The front seat belt retractor disposing structure according to claim 1, wherein said opening is formed at the front surface of said cross member.

6. A front seat belt retractor disposing structure comprising:

a center floor cross member having at least one opening formed at the front surface thereof under a rear seat, through which opening a front seat belt retractor is inserted and is fastened within said floor cross member, said retractor being disposed for a seat belt to be drawn through said opening to the front seat side, and an anchoring member of the retractor fastening the retractor into said cross member, said floor cross member being formed in a hollow inverted U-shaped cross-section in such a manner that the lower opening thereof makes contact with a floor of a vehicle under a rear seat along the traverse direction of the vehicle.

7. The front seat belt retractor disposing structure according to claim 6, wherein one end of said front seat belt is arranged through the center of said front seat.

8. The front seat belt retractor disposing structure according to claim 6, wherein said floor cross member includes a sub floor cross member having a length corresponding to the width of a vehicle and a rising part formed with a predetermined space defined by the surface of the floor and the side surface of a floor tunnel, said sub floor cross member being coupled with a reinforcing member formed with a hollow inverted U-shaped cross-section, said reinforcing member having the same shape as the predetermined space of said sub floor cross member.

9. A front seat belt retractor disposing structure comprising:

a center floor cross member having openings formed at the front and rear surfaces thereof under a rear seat, through which front opening a front seat belt retractor is inserted and is fastened within said floor cross member, said retractor being disposed for a seat belt to be drawn through said front opening to the front seat side, said center floor cross member including a sub floor cross member formed in an inverted U-shaped cross-section with a length corresponding to the width of a vehicle and having a rising part formed with a predetermined space formed by the surface of the floor and the side surface of a floor tunnel, and a reinforcing member formed in a hollow inverted U-shaped cross-section and having the same shape as the opening of said sub floor cross member.

10. The front seat belt retractor disposing structure according to claim 9, wherein one end of said front seat belt is arranged through the center of said front seat.

11. The front seat belt retractor disposing structure according to claim 9, wherein said space is formed in a polygonal shape.

12. The front seat belt retractor disposing structure according to claim 9, wherein said reinforcing member is fastened at its lower end surface to the floor, and at its side surface of the floor tunnel.

13. The front seat belt retractor disposing structure according to claim 9, wherein a side surface of said retractor is formed with an anchoring member at the longitudinal rear end of the side surface on the floor tunnel side of said retractor, a flange is formed at the longitudinal end of the other side, said anchoring member is fastened to the side surface of the floor tunnel, and said flange is fastened to the peripheral edge of the opening of said floor cross member.
