Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a chaise lounge installed in various vehicles, and in particular, at the time of so-called rush, the seat portion can be folded to the backrest side, and the number of passengers is reduced. In this case, the present invention relates to a folding chaise lounge whose seat portion can be deployed like a normal chair.

[0002]

2. Description of the Related Art Especially, in a vehicle in a city, there is a large difference in the number of passengers who use the vehicle at the time of rush hour and when it is not at that time, and various measures for efficiently using the same vehicle are elaborated. ing. The foldable chaise lounge that has been proposed hitherto has a seat portion that can be folded toward the backrest portion to widen the aisle at the time of rush hour, so that a large number of passengers can be placed on it. Although it is smaller due to the folding of the seat, it is a mere obstacle in the actual situation.

Therefore, according to the present invention, when a person ponders whether or not a vehicle which is folded but is present in a vehicle can be effectively used, a chair with a seat folded is a bar stool. I realized that it could be a stool like a chair or a step chair.
That is, the upper end surface of the seat portion folded to the backrest portion side (where the legs of the seated person are in contact when the seat portion is used) and the upper end surface of the backrest portion are substantially the same position, I realized that these could be seats. Also, in particular, the upper end surface of the backrest is usually lower than the neck of the person sitting in the deployed seat and lower than the waist of the person standing in the aisle. Yes, its position is almost the same as the seat of the bar stool.

However, when the hips are actually put on the folded seat and backrest of the conventional folding chaise lounge, the hips and hips come into contact with the window glass of the vehicle,
If pushed in that state, the window glass of the vehicle 90
It was thought that it would almost break. If so,
It seems that a protection bar should be provided inside the window glass 90, but this time, this protection bar will hit the head of a person sitting in the chaise lounge at normal times, and the protection bar will be attached to the vehicle. It is not suitable in any case because it requires work.

Therefore, the inventors of the present invention used the folding chaise lounge with the seat portion folded as a so-called stool during commuting, and
As a result of various investigations on how to protect the user and the window glass in that case, as a result of arranging the support part on the upper side of the backrest part, this support part acts as a seat part. The present invention has been completed by newly discovering that raising and lowering depending on the situation produces a good result.
