Abstract

<P>PROBLEM TO BE SOLVED: To provide a back pad cushion mitigating fatigue of the waist and the back of a driver by an approaching/separating cushion with resiliency, when the back abutment part is pushed by the back of a user, warping a back pad abutment part and a back abutment part into an approximately U shape and approaching them to each other with resiliency by an elastically deformable spring member and, when the pushing to the back abutment part by the back of the user is weakened, separating the back pad abutment part and the back abutment part with elasticity by the spring member, improving the versatility of the use by enabling the detachment of a cushion body, and reducing the manufacturing cost by simplifying the structure. <P>SOLUTION: This back pad cushion is provided with the cushion body 4 formed of the back pad abutment part 5 abutting on a back pad part 2 and the back abutment part 6 abutting on the back W<SB>1</SB>of the user and the spring member 7 capable of resiliently warping and deforming the back pad abutment part and the back abutment part mutually into approximately U shape in the cushion body. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a back cushion for use in various types of vehicles such as long-distance trucks, buses, ordinary vehicles, construction machines, office chairs, and home chairs.

Conventionally, as this type of back cushion, the back rest of the seat body and the back of the user are provided so as to be interposed between the back rest and the back of the user. The thing of the structure provided with the back contact part which can contact | abut on the back is known.
JP-A-6-78838

  However, in the case of this conventional structure, since the compression spring is provided between the back contact portion and the back contact portion, the structure is likely to be complicated and heavy, and the manufacturing cost cannot be reduced. Have the inconvenience.

  The present invention aims to solve these disadvantages. Among the present inventions, the invention according to claim 1 can be interposed between the backrest portion of the seat body and the back of the user. Provided with a back contact part that can contact the back support part and a back contact part that can contact the back of the user, and the back contact part and The back contact cushion is provided with a spring member that is elastically deformable by warping the back contact portions in a substantially U shape.

  The invention according to claim 2 is characterized in that the spring member is made of a substantially U-shaped leaf spring material, and the invention according to claim 3 is characterized in that the seat abuts on the back abutment portion. A non-slip body capable of coming into contact with the backrest portion of the body is provided.

  As described above, according to the present invention, the cushion body is interposed between the back portion of the seat body and the back of the user, and the back contact portion of the cushion body is the seat. The back abutment part and the back abutment part abut against the back of the user, and when the back abutment part is pressed by the user's back, the back abutment abutment part and the back abutment part are A spring member that is warped in an approximately U shape and can be elastically deformed and closes with elasticity, and when the pressure of the back contact portion by the user's back is weakened, the back contact contact portion and the back contact portion are elastic by the spring member. It is possible to relieve fatigue of the driver's waist and back by the cushion of proximity and separation with elasticity, and the cushion body can be used as a backrest part of the seat body even during driving. It can be placed anywhere between the user's back , Can also be removed cushion body, it is possible to increase the flexibility of use, further, the structure can also be simplified, thereby reducing the manufacturing cost.

  In the invention described in claim 2, since the spring member is made of a substantially U-shaped leaf spring material, the structure can be further simplified and the weight can be reduced. In the described invention, the backrest contact portion is provided with a non-slip body capable of contacting the backrest portion of the seat body, so that the cushion body is positioned at an arbitrary position on the backrest portion of the seat body. It can be fixed, and the convenience of use can be further enhanced.

  1 to 5 show an embodiment of the present invention. Reference numeral 1 denotes a seat body, for example, a seat body of a long-distance truck, bus, ordinary car, construction machine, or office or household chair. The seat body 1 includes a backrest portion 2 and a seat portion 3.

4 is a cushion body, interposed capable disposed between the back W ₁ of the backrest 2 and the user W of the seat body 1, which can abut against the backrest 2 of the seat body 1 A back abutment portion 5 and a back abutment portion 6 capable of abutting against the back W _{1 of the} user W are provided, and the back abutment abutment portion 5 and the back abutment portion 6 can be elastically deformed by warping each other in a substantially U shape. A simple spring member 7 is provided.

In this case, the spring member 7 is made of a substantially U-shaped leaf spring material 8, and a mounting plate 9 is attached to one outer surface of the spring member 7 on the backrest portion 2 side by a fastening member 10. _A mounting plate 11 is attached to the other outer surface on the _one side by a fastening member 12, and the mounting plate 9 has a plate-like shape having a concave groove 13 a made of rubber or synthetic resin that can contact the backrest portion 2 of the seat body 1. A non-slip body 13 is attached by adhesion or the like, a cushion material 14 made of an elastic material is attached to the attachment plate 11, and the whole is covered with a cover material 15 such as cloth.

Since this embodiment has the above-described configuration, as shown in FIG. 4, two cushion bodies 4 are interposed between the backrest portion 2 of the seat body 1 and the back W _{1 of the} user W so as to cushion the cushion body 4. The back abutment portion 5 of the body 4 abuts on the back abutment portion 2 of the seat body 1 and the back abutment portion 6 abuts on the back W ₁ of the user W. At this time, the back of the user W When the back abutting portion 6 is pressed by W ₁ , the back abutment portion 5 and the back abutting portion 6 are warped in a substantially U shape and are brought close to each other with elasticity by a spring member 7 which can be elastically deformed, and the user W's When the pressure of the back contact portion 6 by the back W ₁ is weakened, the back contact contact portion 5 and the back contact portion 6 are separated with elasticity by the spring member 7, and the proximity separation cushion with the elasticity is used. Can relieve the driver's waist and back fatigue, and the cushion body 4 can be used while driving. Some can be interposed at any position between the back W ₁ of the backrest 2 and the user W of the seat body 1, can also be arranged a plurality, for example two or cushioning body 4, The cushion body 4 can be removed, the flexibility of use can be increased, the structure can be simplified, and the production cost can be reduced.

  In this case, since the spring member 7 is made of a substantially U-shaped leaf spring material 8, the structure can be further simplified and the weight can be reduced. Since the non-sliding body 13 that can contact the back rest portion 2 of the seat body 1 is provided, the cushion body 4 can be fixed to the back rest portion 2 of the seat body 1 at an arbitrary position for further use. Can improve convenience.

In addition, as shown in FIG. 5, the cushion body 4 can be installed on the floor surface, and the head W _{2 of the} user W can be put on it, so that it can be used as a nap or portable pillow.

  Note that the present invention is not limited to the above-described embodiments, and is not limited to seats for various vehicles such as long-distance trucks, buses, ordinary vehicles, and construction machines, but various seats such as office and home chairs. The structure and form of the seat body 1, the back contact portion 5, the back contact portion 6, and the spring member 7 are appropriately designed and changed.

  As described above, the intended purpose can be sufficiently achieved.
