Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seat with a backrest that is attached to a motorcycle such as a motorcycle or a scooter that is ridden astride the seat, and is particularly applicable to a large motorcycle. This relates to sheets used for.

t-1 Seat 1J- In saddle-riding vehicles, especially small motorcycles, the driver's lower body is held against the vehicle body by the so-called knee grip, which involves repositioning the driver and pinching both knees between the seat and the side cover below the seat. was.

However, when motorcycles become larger and are driven over long distances for long periods of time, supporting the rider's lower body with the aforementioned knee grips may cause the rider to get tired.

The present invention relates to an improvement of a seat for a saddle-riding type vehicle that solves the above-mentioned problems. A waist clamping member that clamps the waist of a seated person is attached to one side of the seat so that it can be opened and closed to the left and right, and both waist clamping members are connected to each other via a transmission mechanism and are connected to an operating member. Therefore, when the operating member is operated, the waist clamping members are appropriately opened and closed to the left and right via the surface transmission mechanism, and the waist of the seated person is clamped by the waist clamping members.
