Description

  The present invention relates to an automobile seat, and more particularly to an automobile seat with a protrusion having a protrusion on a backrest portion.

  In the conventional car seat, there is a problem that when the car is driven for a long time, the back and waist become painful.

  In this regard, Patent Document 1 proposes an automobile seat having three ribs on the backrest portion.

However, in the automobile seat described in Patent Document 1, there is a problem that the left and right ribs push back muscles and the back becomes painful. In addition, since the difference in system between individuals is not taken into account, there is a problem that even if the position and size are right for some people, it hurts for others.
Japanese Patent Laid-Open No. 5-130922

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a car seat with a protrusion that does not hurt the back even when driven for a long time.

  In order to achieve this object, the present invention has a semi-cylindrical shape in which a substantially cylindrical column is cut by a surface substantially perpendicular to the bottom surface, is formed of an elastic material, and holds gas therein. Provided is a car seat with a protrusion, which includes a space and a valve that can be opened and closed to allow gas to enter and leave the space, and includes a protrusion that is detachably attached by a hook-and-loop fastener.

  According to the automobile seat with a projection of the present invention, the back does not hurt even if it is driven for a long time, it can be removed when not needed, and it can flexibly cope with differences in body shape due to individual differences. There is. In addition, there is an effect that the body is less likely to shake during driving.

  Hereinafter, an embodiment of a vehicle seat with a projection of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an automobile seat with protrusions according to the present embodiment. As shown in FIG. 1, the automobile seat 1 with protrusions having the protrusions according to the present embodiment has a semi-cylindrical shape obtained by cutting a substantially cylindrical column body by a surface substantially perpendicular to the bottom surface, and has elasticity. The protrusion 10 is formed of a material and is arranged so that the semi-cylindrical center line C1 comes to the longitudinal center axis C0 of the backrest portion.

  Here, the longitudinal center axis C0 of the backrest portion is an axis that is symmetric when the headrest is on the top. Further, the center line C1 of the protruding portion 10 indicates an axis that is symmetric when the longitudinal direction is arranged vertically.

  FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1 of the automobile seat with a protrusion according to the present embodiment. In FIG. 2, the example which attaches the projection part 10 to the flame | frame part 20 of a sheet | seat is demonstrated. That is, the protrusion 10 can be provided inside the sheet. Note that the protrusion 10 may be attached to a cushion part attached to the frame part 20. Further, the protrusion 10 can be attached to the surface of the sheet.

  As shown in FIG. 2, the protrusion 10 is attached with the flat portion of the protrusion 10 aligned with the frame 20. The protrusion 10 is fixed to the frame 20 using an adhesive or a double-sided tape.

  FIG. 3 is a cross-sectional view of the automobile seat with a protrusion according to the present embodiment taken along line BB in FIG. As shown in FIG. 3, the protrusion 10 is attached to the surface of the backrest portion of the seat where the human back hits. It is even better to install a protrusion to secure the scapula.

  FIG. 4 is an external perspective view of the protrusion 10. As shown in FIG. 4, the protrusion 10 has a semi-cylindrical shape in which a substantially cylindrical column is cut by a surface substantially perpendicular to the bottom surface. In the present embodiment, the semi-cylindrical shape includes a cylindrical shape whose bottom surface is a curved surface. That is, the protrusion 10 of the present embodiment does not need to have a flat bottom surface.

  When the protrusion 10 has a width φ, that is, when the protrusion 10 has a semi-cylindrical shape, the length of the chord on the bottom surface is preferably 5 cm or more and 15 cm or less, but is not limited thereto. Further, the length L in the longitudinal direction is preferably 15 cm or more and 35 cm or less, but is not limited thereto. Further, the thickness T is preferably 1 cm or more and 5 cm or less, but is not limited thereto.

  The protrusion 10 may be made of any material having elasticity. Examples include, but are not limited to, urethane sponge, polyethylene, and silicon rubber.

  FIG. 5 is a cross-sectional view of the protrusion 10 having a valve. As shown in FIG. 5, the protrusion 10 can be configured to include a space 15 that holds gas therein and an openable / closable valve 30 that allows gas to enter and leave the space 15.

  Since the protruding portion 10 is formed of an elastic material, the size of the protruding portion 10 can be adjusted by taking air into and out of the space 15 of the protruding portion 10.

  The protrusion 10 can be configured to be detachably attached to the backrest of the seat. In this case, a hook-and-loop fastener such as Velcro (registered trademark) can be used.

  As described above, the automobile seat with protrusions according to the present embodiment is formed of an elastic material and includes a protrusion having a curved surface on the backrest portion. For this reason, there is an effect that the back does not hurt even if driving for a long time.

  Further, in the automobile seat with protrusions of this embodiment, the protrusions are detachably attached to the sheet. For this reason, there is an effect that it can be removed when unnecessary.

  Furthermore, the size of the automobile seat with protrusions according to the present embodiment can be changed by taking air in and out. For this reason, there is an effect that it is possible to flexibly cope with differences in body shape due to individual differences. In addition, there is an effect that the body is less likely to shake during driving.

  The automobile seat with protrusions of the present invention can be used not only for automobiles but also for airplanes and passenger ships.

It is a perspective view of a car seat with a projection of this embodiment. It is the sectional view on the AA line of FIG. 1 of the automobile seat with a protrusion of this embodiment. It is the BB sectional view taken on the line of FIG. 1 of the vehicle seat with a protrusion of this embodiment. It is an external appearance perspective view of a projection part. It is sectional drawing of the projection part which has a valve | bulb.
