Abstract

(57) [Summary] (Modifications) [PROBLEMS] To achieve dehumidification and cooling of the crotch portion of a motorcycle seat at the lowest cost and with an extremely simple configuration. The present invention forms a ventilation groove (2) in the front-rear direction of a cushioning material (1) for a seat or a bottom plate (4).
Dehumidification and cooling of the crotch are solved by a very simple structure.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a seat having a ventilation groove in a motorcycle, a scooter, or the like.

[0002]

[Prior art]

 Conventional motorcycles, scooters, and other seats tend to emphasize ride comfort, and as a result, technologies centered on cushioning materials have made remarkable progress.

[0003]

[Problems to be solved by the invention]

 Seats for motorcycles, scooters, etc. become hot and humid in the summer months, and the crotch area becomes stuffy even during running, which makes them uncomfortable and unsanitary. That is what we are trying to solve.

[0004]

[Means for solving the problem]

 The present invention addresses these problems by applying the phenomenon that the temperature and humidity drop significantly due to the Venturi effect that occurs when the wind traveling through the ventilation groove formed in the seat body passes through the crotch part of the occupant. Have solved the point.

[0005]

[Embodiment of the invention]

 The most suitable material for the seat of the present invention is a low-density closed-cell polyurethane self-skinning foam. This material is a cushioning material, but the surface has the property of forming a self-skin structure. Furthermore, since the cells are closed cells, rainwater and moisture do not enter the cushioning material. Since several drain holes are provided in the ventilation groove of the seat body, rainwater and the like do not accumulate. Also, by attaching a net made of synthetic resin or the like to the ventilation groove, the rigidity of the left and right portions of the seat body and the aesthetic commercial value are improved. In addition, the venturi effect generated in the ventilation groove has the same characteristics.

[0006]

【Example】

 An embodiment will be described with reference to the accompanying drawings. 1 is a self-skinning foam material with low-density closed cells, which is a sheet body integrally molded with ventilation grooves. 2 is a ventilation groove part. 3 is a drain hole for drainage. 4 is the bottom plate. 5 is a net made of synthetic resin. Reference numeral 6 denotes a traveling wind path while passing through the ventilation groove at the crotch portion of the seat body.

As shown in FIG. 5 at 6, as the speed of the motorcycle increases, a negative pressure due to the traveling wind is generated around the passenger behind, so that a venturi effect occurs at the rear of the ventilation groove. The Venturi effect has the same characteristics even in the case of two passengers.

[0008] The sheet bottom plate shown in FIG. 3 is a sheet manufacturing means which gives the same Venturi effect in principle at the lowest cost. First, a motorcycle seat bottom plate is characterized in that the ventilation groove 2 is formed in the bottom plate 4 in the front-back direction of the seat, and the cushion material 1 is divided right and left by an adhesive or the like.

[0009]

[Effect of the invention]

 (1) The seat of the present invention has a ventilation groove that is not seen in the past, so that dehumidification and cooling of the occupant's crotch can be performed at the same time, so that the seat is comfortable and sanitary. 2 Does not require equipment for simultaneous dehumidification and cooling. 3 A novel design that has never existed before can be made. (4) It is possible to eliminate sheet manufacturing process and waste of materials. 5. By attaching the net to the ventilation groove, the aesthetic product value can be improved.

[Brief description of the drawings]

FIG. 1 is an overall perspective view of a basic seat of the present invention.

FIG. 2 is an overall perspective view in which a ventilation net is attached to a ventilation groove of a sheet in FIG. 1;

FIG. 3 is an overall perspective view of the bottom plate having ventilation grooves according to the present invention.

FIG. 4 is a sectional view taken along line AA of FIG. 1;

FIG. 5 is a side view and a partial sectional view of a traveling wind path during traveling.
