Description

[Detailed Description of the Invention] The present invention mainly relates to a seat device for a passenger in a two-wheeled motor vehicle.

Conventional devices of this type include a sheet provided on the top surface of the vehicle body, which is attached to the vehicle body side via a pair of hinge members connected to each other by pins inserted into pin holes so as to be openable and closable. As is known, in this case, the pair of hinge members are generally integrally connected to each other via the pin, so that vibrations from the vehicle body are transmitted through this. This is accompanied by the inconvenience of being transmitted to the seat side.

The purpose of the present invention is to obtain a device that does not have such inconveniences.
A pin 5 inserted into the pin holes 3 and 4 is provided.
In the type of hinge member 6, 7 which is connected to each other by a pair of hinge members 6, 7, which are attached to the vehicle body 1 in an openable and closable manner, at least one of the pin holes 3, 4 is connected to the pin 5.
The pair of hinge members 6 and 7 have recesses 8 and 9 that face each other in the closed position, and an intermediate portion thereof is fitted into the recesses 8 and 9. and an elastic member 10 that is compressed from above and below.

Each of the hinge members 6 and 7 is shaped like a downward and upward frame housing, and the recesses 8 and 9 are generally formed integrally therewith, but, for example, as shown in FIG. 5, they may be prepared separately in advance. It is also possible to use a type in which the groove-shaped pieces 8a and 9b are fixed by welding or other means. Furthermore, in the illustrated example, a hinge-like arm member 1 is formed between the two members 8 and 9 by fitting the root portion to the outer periphery of the pin 5.
1, a pair of left and right notches 12, 12 are formed therein, and each elastic member 10, 10 is fitted and supported in the pair of left and right notches 12, 12. It should be noted that each elastic member 10 was arranged so that the protrusion 13 formed on each side surface faced into the through hole 14 on each side surface of the lower sheet member 9.

In this way, according to the present invention, at least one of the pin holes 3 and 4 is made into a blank hole, and some play is formed between both hinge members 6 and 7, thus preventing the transmission of vibration. Furthermore, both members 6, 7 compress an intermediate elastic member 10 in their closed position, so that the seat 2 can be elastically supported; This is fitted into the recesses 8 and 9 of the two members 6 and 7, and has the effect of preventing misalignment between the two members 6 and 7.
