Abstract

A seat structure for a vehicle comprises a seat, a seat rail comprising a lower rail and an upper rail, and an anchor bracket fixing an anchor (a first anchor) of a seatbelt device to the upper rail. The anchor bracket includes a first bracket provided with a first bottom portion fixed to the upper rail and a first side portion rising upwardly from the first bottom portion and a second bracket provided with a second bottom portion fixed to the upper rail, a second side portion rising upwardly from the second bottom portion, and an anchor attachment portion where the anchor is attached. The first side portion and the second side portion are joined together, overlapping each other in a vehicle width direction, and the first bracket extends forwardly beyond the second bracket.

First claim

What is claimed is:

1. A seat structure for a vehicle, comprising:
a seat where an occupant is seated;
a seat rail fixed to a vehicle body, the seat rail comprising a lower rail including a groove portion extending in a vehicle longitudinal direction and an upper rail provided to be slid in the groove portion of the lower rail and guided by the lower rail; and
an anchor bracket fixing an anchor of a seatbelt device for restraining the occupant to the upper rail of the seat rail,
wherein said anchor bracket includes a first bracket provided with a first bottom portion fixed to said upper rail and a first side portion rising upwardly from said first bottom portion and a second bracket provided with a second bottom portion fixed to said upper rail, a second side portion rising upwardly from said second bottom portion, and an anchor attachment portion where said anchor is attached,
said first side portion of the first bracket and said second side portion of the second bracket are connected to each other and positioned such that a line extending in a vehicle width direction intersects both said first side portion of the first bracket and said second side portion of the second bracket, and
said first bracket is provided to extend forwardly beyond said second bracket at an upper surface of said upper rail of the seat rail.

2. The seat structure for the vehicle of claim 1 , wherein said first bracket is longer than said second bracket in the vehicle longitudinal direction.

3. The seat structure for the vehicle of claim 1 , wherein said first side portion of the first bracket is positioned more closely to said seat than said second side portion of the second bracket.

4. The seat structure for the vehicle of claim 1 , wherein a joint part of said first side portion of the first bracket to said second side portion of the second bracket is configured to have a hat-shaped cross section.

5. The seat structure for the vehicle of claim 1 , wherein said second bracket includes a rigidity reinforced part which is provided at a front end part of said second bottom portion.

6. The seat structure for the vehicle of claim 1 , wherein said second bracket is provided with a third side portion which is provided to rise upwardly from said second bottom portion and faces said second side portion, and said anchor attachment portion is provided at said third side portion.

7. The seat structure for the vehicle of claim 1 , wherein said first bracket is provided to extend over a range from a front end portion and a rear end portion of said upper rail of the seat rail.

8. The seat structure for the vehicle of claim 7 , wherein said second bottom portion of the second bracket is fixed to said upper rail of the seat rail in a state where the second bottom portion overlaps on said first bottom portion of the first bracket.

9. The seat structure for the vehicle of claim 1 , wherein said second bracket fixed to the upper rail is provided to protrude outwardly, in the vehicle width direction, beyond the upper rail.

10. A seat structure for a vehicle, comprising:
a seat where an occupant is seated;
a seat rail fixed to a vehicle body, the seat rail comprising a lower rail including a groove portion extending in a vehicle longitudinal direction and an upper rail provided to be slid in the groove portion of the lower rail and guided by the lower rail; and
an anchor bracket fixing an anchor of a seatbelt device for restraining the occupant to the upper rail of the seat rail,
wherein said anchor bracket includes a first bracket and a second bracket,
said first bracket is provided with a first bottom portion fixed to said upper rail and a first side portion rising upwardly from said first bottom portion,
said second bracket is provided with a second bottom portion fixed to said upper rail, a second side portion rising upwardly from said second bottom portion, and an anchor attachment portion where said anchor is attached,
said first bracket is longer than said second bracket in the vehicle longitudinal direction,
said first bracket is provided to extend forwardly beyond said second bracket at an upper surface of said upper rail of the seat rail and extend over a range from a front end portion and a rear end portion of said upper rail of the seat rail,
said second bracket fixed to the upper rail is provided to protrude outwardly, in the vehicle width direction, beyond the upper rail,
said first side portion of the first bracket and said second side portion of the second bracket are connected to each other and positioned such that a line extending in a vehicle width direction intersects both said first side portion of the first bracket and said second side portion of the second bracket,
said first side portion of the first bracket is positioned more closely to said seat than said second side portion of the second bracket,
a joint part of said first side portion of the first bracket to said second side portion of the second bracket is configured to have a hat-shaped cross section,
said second bracket includes a rigidity reinforced part which is provided at a front end part of said second bottom portion,
said second bracket is provided with a third side portion which is provided to rise upwardly from said second bottom portion and faces said second side portion, and said anchor attachment portion is provided at said third side portion, and
said second bottom portion of the second bracket is fixed to said upper rail of the seat rail in a state where the second bottom portion overlaps on said first bottom portion of the first bracket.

11. A seat structure for a vehicle, comprising:
a seat where an occupant is seated;
a seat rail fixed to a vehicle body, the seat rail comprising a lower rail including a groove portion extending in a vehicle longitudinal direction and an upper rail provided to be slid in the groove portion of the lower rail and guided by the lower rail; and
an anchor bracket fixing an anchor of a seatbelt device for restraining the occupant to the upper rail of the seat rail,
wherein said anchor bracket includes a first bracket provided with a first bottom portion fixed to said upper rail and a first side portion rising upwardly from said first bottom portion and a second bracket provided with a second bottom portion fixed to said upper rail, a second side portion rising upwardly from said second bottom portion, and an anchor attachment portion where said anchor is attached,
said first side portion of the first bracket and said second side portion of the second bracket are connected to each other and positioned such that a line extending in a vehicle width direction intersects both said first side portion of the first bracket and said second side portion of the second bracket,
said first bracket is provided to extend forwardly beyond said second bracket at an upper surface of said upper rail of the seat rail,
said second bracket includes a rigidity reinforced part which is provided at a front end part of said second bottom portion, and
said second bracket fixed to the upper rail is provided to protrude outwardly, in the vehicle width direction, beyond the upper rail.
