  By the way, in the massage chair etc. which are used in a residence etc., there are some which can massage not only a back part but a shoulder part. In such a massage chair, a rigid hammer or roller protrudes from the seating surface toward the seated person and operates from top to bottom to press the shoulder of the seated person. In addition, there is a type in which the amount of protrusion of the hammer or roller increases upward in the back massage in accordance with the curvature of the back toward the shoulder. However, since various vibrations and vibrations occur during traveling in the vehicle compartment, when a rigid body that protrudes from the seating surface toward the occupant is provided, the rigid body is bent toward the shoulder from the occupant's shoulder or back (hereinafter referred to as the shoulder). There is a risk of contact with a portion other than a desired portion such as a peripheral portion. In addition, if a rigid body such as a massage hammer is provided through a pad, the hammer does not have a pad, so there is a high possibility that an uncomfortable feeling will occur when sitting, especially when it is shaken.

  In view of the above, an object of the present invention is to provide a vehicle seat that is less uncomfortable when seated and that can massage the back and shoulders of the seated person or the shoulder periphery.

As means for solving the above problems, the first invention of the present invention is a vehicle seat having a seat back including a frame, a pad constituting the entire seating surface, and massage means, wherein the pad is A plurality of holes extending vertically from the seating surface to the opposite surface are provided, and the massage means includes a plurality of massage members that are elastically deformable while being elastically deformable by inhaling and discharging gas.

The vibration means 47 is fixed to the support spring 24 b via a vibration means base plate 48 that can be fixed in the same manner as the base plate 43. Thereby, the vibration generated by the vibration means 47 can be transmitted to the three sets of massage members 12 fixed to the lower base plate 43b.

  The seat back 4 is assembled by fixing the base plates 43 a and 43 b to which the massage member 12 is attached and the vibration means base plate 48 to which the vibration means 47 is attached to the frame 20 and assembling the pad 26 and the cover 28 to the frame 20. It is done.

  Next, a method for using the vehicle seat 1 will be described. FIG. 4 shows a state of the seat back 4 of the vehicle seat 1 in a natural state. The seating surface of the seat back 4 is formed in a shape having a smooth curved surface by the cover 28 being stretched. At this time, the pad 26 maintains its natural state except that the pad 26 contracts due to the tension of the cover 28. In addition, the plurality of massage members 12 of the massage means 10 are in contact with the cover 28 in a substantially natural state or are retracted from the cover 28. At this time, as shown by a broken line X in FIG. 4, the uppermost massage members 12a and 12b have elastic deformation and expansion / contraction directions of the other massage members 12c to 12h indicated by a broken line Y. Compared to the direction, it is heading downward and forward. That is, the upper frame 20a is bent with respect to the lower frame 20b. By arranging the support spring 24a and the upper base plate 43a in parallel with the upper frame 20a, the uppermost massage members 12a and 12b are Compared to the other massage members 12c to 12h, it faces downward toward the front of the seat.

  FIG. 5 shows a state in which the seat back 4 of the vehicle seat 1 is reclined and the persons A and B are seated. At this time, the pad 26 and each massage member 12 deform | transform according to the pressure received by a seated person's back. The seating surface of the pad 26 and the most protruding surface of the lid portion 50b of the massage member 12 exist on the same surface along the back surface of the seated person. When the massage member 12 is elastically deformed together with the pad 26, the hit of the massage member 12 against the back of the seated person can be eased, and a sense of incongruity hardly occurs. In particular, when the elastic deformability of the massage member 12 is approximated to the pad 26, the uncomfortable feeling can be reduced or eliminated. In FIG. 5, since the seated person's body is not in contact with the massage members 12a and 12b attached to the upper frame 20a and the periphery thereof, these portions generally maintain a natural state.

  In the state of FIG. 5, the back of the seated person (humans A and B) can be massaged by operating the massage means 10. By supplying gas to the massage members 12a to 12h by the drive means 14 and the control means, the massage members 12a to 12h can be extended in the direction indicated by the imaginary line in FIG. With this extension pressure, the back of the seated person can be pressed. Moreover, by discharging the gas in the massaging members 12a to 12h by the control means, the massaging members 12a to 12h can be contracted to make the pressure lower than that at the time of extension or to be separated from the back of the seated person. By repeatedly sucking and discharging gas, the pressed state and the non-pressed state can be repeated, and massage can be performed.

  Here, the massage members 12c to 12h can press the back of the seated person almost perpendicularly to the back. Further, by activating the vibration means 47, a massage that receives vibration through the lower base plate 24b and imparts vibration in addition to pressing can be performed.

  The uppermost massage members 12a and 12b press the shoulder peripheral portion against the larger person A. Since the massage members 12a and 12b face the lower front direction as compared to the massage members 12c to 12h, the massage members 12a and 12b are pressed against the human A's shoulder peripheral portion at an angle closer to vertical. Therefore, it is possible to massage by applying a direct pressing force to the shoulder periphery. On the other hand, in the smaller person B, the lower parts of the massage members 12a and 12 weakly press the shoulder portion or the shoulder peripheral portion from the shoulder portion to the neck.

  6 shows a state where the person B is seated when the seat back 4 is further folded from the state shown in FIG. At this time, the angle of the massage members 12a and 12b at the uppermost position changes with the middle break. In the position shown in FIG. 6, the uppermost massage members 12a and 12b are positioned so as to cover the shoulders of the person B, and press the shoulders and the shoulder peripheral parts of the person B at an angle closer to the vertical. It is possible to do.

  In this vehicle seat 1, the portion of the massage means 10 that presses the seat occupant is elastically deformed by the load of the seat occupant, so that it is difficult to feel the massage member 12 as a foreign object when seated. On the other hand, at the time of massaging, the plurality of massaging members 12 act on the back, shoulder, or shoulder periphery of the seated person without going through the pad 26, respectively, so that direct pressing with higher pressure is possible. Therefore, the function of the massage is kept higher even though the uncomfortable feeling in the sitting state is reduced.

  In addition, among the plurality of massage members 12a to 12h, the uppermost massage members 12a and 12b can be expanded and contracted in the lower front direction compared to the other massage members 12c to 12h. For this reason, the other massage members 12c to 12h are provided at an angle at which the waist and the back can be pressed more vertically, and the uppermost massage members 12a and 12b are provided at an angle at which the shoulder or the shoulder periphery can be pressed more vertically. Is possible. Therefore, in this vehicle seat 1, effective massage can be performed not only on the back portion and the waist portion, but also on the shoulder portion and the curved portion toward the shoulder portion, and the massage function is improved.

  In particular, in the vehicle seat 1 of the present embodiment, the massage members 12a and 12b at the uppermost position are provided in a part that is folded in the middle folding seat back, that is, the upper frame 20a. It is possible to change the angle further downward. Therefore, by adjusting the angle of folding, it is possible to set the positions of the massage members 12a and 12b at a position according to the body shape of the seated person or at a desired part of the shoulder portion or the shoulder peripheral portion. An effective massage can be given to human beings.

  The vehicle seat according to the present invention is not limited to the above embodiment. The vehicle seat may be a passenger seat, a middle seat, a rear seat, or a driver seat. Of course, the sheet may not be folded.

  A desired number of massage members in the massage means can be provided at desired positions on the seating surface. Further, the massage member below the uppermost massage member may be arranged in the elastic deformation in the front lower direction and the expansion / contraction direction as compared with the elastic deformation and expansion / contraction direction of the massage member below the massage member. Moreover, it is preferable that a massage member is provided so that it may become left-right symmetric with respect to the vertical centerline of a seat back like this embodiment, for example, the both right and left sides may be integrated. Of course, it may be provided asymmetrically.

  The structure of a massage member is not limited to the said embodiment, It can be set as various structures. For example, the massage member can be composed of a cylinder, a piston that moves in the cylinder, and an elastic member provided between the cylinder and the piston, such as a coil spring or a rubber ball. In this configuration, the piston is provided to be elastically movable with respect to the cylinder by the elastic member. Further, it can be configured to be able to expand and contract by forming the gas between the cylinder and the piston or inside the rubber ball so that the gas can be sucked and discharged, and moving the piston with the gas pressure. Alternatively, the massage member can be constituted by a gas bag positioned on the seating surface side and an elastic member such as a coil spring, a spring, or rubber that instructs the gas bag from the side opposite to the seating surface. In this case, the elastic member is formed to be elastically deformable, and the gas bag can be expanded and contracted toward the seating surface by sucking and discharging the gas. In any configuration, the configuration of a preferable massage member in the present invention is a configuration in which an elastically deformable portion and a portion that expands and contracts by gas suction and discharge are the same. In this configuration, it is possible to further contract the massage member from the compressed state in the elastic deformation by discharging gas, that is, by creating a negative pressure in the massage member. Therefore, during massage, a state in which the back, shoulder, or shoulder periphery of the seated person is pressed and a state in which the seat is not pressed can be formed, and more effective massage is possible.
