Abstract

There is provided a seat opening/closing structure for a saddle riding vehicle that suppresses the cost and simplifies the structure to enhance usability. A seat hinge 31 has a vehicle-body-side hinge 51 A provided to a vehicle body side, and a seat-side hinge 52 which is turnably secured to the vehicle-body-side hinge 51 A through a hinge pin 55 . The seat-side hinge 52 has a projecting portion 52 h extending to the vehicle-body-side hinge 51 A, the vehicle-body-side hinge 51 A is provided with a leaf spring 64 having a top portion 64 a with which the projecting portion 52 h can come into contact, and the projecting portion 52 h gets over the top portion 64 a of the leaf spring 64 when the seat is opened, whereby the seat-side hinge 52 is supported by the leaf spring 64 and the seat is kept under an open state.

First claim

The invention claimed is:

1. A seat hinge structure for a saddle riding vehicle in which an occupant-riding seat is freely opened and closed with respect to a vehicle body through a seat hinge provided to one end of the seat, characterized in that the seat hinge has a vehicle-body-side hinge provided to the vehicle body, and a seat-side hinge which is turnably secured to the vehicle-body-side hinge through a hinge pin, the seat-side hinge is provided with a projecting portion extending to the vehicle-body-side hinge, and the vehicle-body-side hinge is provided with a leaf spring having a convex portion capable of coming into contact with the projecting portion, whereby the projecting portion gets over the convex portion of the leaf spring when the seat is opened and the seat-side hinge is supported on the leaf spring to keep the seat under an open state.

2. The seat hinge structure for the saddle riding vehicle according to claim 1 , wherein a plurality of leaf springs are laminated to form a laminated leaf spring.

3. The heat hinge structure for the saddle riding vehicle according to claim 1 , wherein the leaf spring is a member having a substantially V-shaped cross-section, and is disposed so that an opening of the V-shape faces the hinge pin in side view.

4. The seat hinge structure for the saddle riding vehicle according to claim 1 , wherein the seat is opened and closed while supported by only the hinge pin over the range from a seat holding state under which the seat is held at a halfway position between a full-close position and a full-open position of the seat to a seat full-open state under which the seat is fully opened.

5. The seat hinge structure for the saddle riding vehicle according to claim 1 , wherein the leaf spring comes into contact with the projecting portion and the vehicle-body-side hinge through a curved face of the leaf spring.

6. The seat hinge structure for the saddle riding vehicle according to claim 1 , wherein a plate for supporting the leaf spring is provided to the upper face of the vehicle-body-side hinge, the plate is provided with ribs having curved surfaces along the leaf spring, and the leaf spring is supported by the ribs.

7. The seat hinge structure for the saddle riding vehicle according to claim 6 , wherein a recess portion in which the plate is inserted is formed on the vehicle-body-side hinge, a recess portion in which the projecting portion is mounted is formed on the plate, and each of both the recess portions is provided with a drain hole.

8. The seat hinge structure for the saddle riding vehicle according to claim 1 , wherein an article storage box provided below the seat has a seal face which comes into contact with the lower portion of the seat, and the seat hinge is disposed outside the seal face.

9. The seat hinge structure for the saddle riding vehicle according to claim 6 , wherein the plate has an opening portion ( 58 c ), and the projecting portion of the seat-side hinge can be supported by a projecting portion of the leaf spring which projects from the opening portion ( 58 c ).

10. The seat hinge structure for the saddle riding vehicle according to claim 1 , wherein the leaf spring is formed to be linearly symmetrical in cross-section.

11. The seat hinge structure for the saddle riding vehicle according to claim 6 , wherein the plate has a frontwards ascending front wall forming the recess portion, a surface at the front side of the front wall faces the seat-side hinge, the ribs are formed on a surface at the back side of the front wall, and the surface at the front side is overlapped with an arc drawn with the hinge pin as the center thereof in side view.
