Description of the Related Art In a seat device installed in a cabin forming part of a vehicle and used for seating an occupant, the seat device stably supports the occupant seated thereon and provides a good sitting comfort to the occupant seated thereon. It is required to feel. In order to satisfy these requirements, for example, when the vehicle is in a turning traveling state, lateral swings occurring in the seat cushion and the seat back are appropriately suppressed, and the posture of the seated occupant is not lost. Function, and appropriately absorb vibrations having various frequencies transmitted to the seat cushion and the seat back as the vehicle travels, and the vibrations accompanying the vehicle travel directly to the seated occupant. There is a need for a function that does not work.

ング部材とによって座圧受け部が形成されている。In such a seat device, in order to make a seated occupant feel good sitting comfort, transmission of vibration transmitted to a seat cushion through a floor portion in a vehicle compartment forming portion to a seated occupant is suppressed. In order to achieve this, the seat pressure receiving portion that forms the upper portion in the seat cushion and receives the seat pressure of the seated occupant is provided on the floor portion in the vehicle compartment forming portion. It is effective to adopt a configuration in which the fixed portion forming the lower portion of the cushion is supported by the spring member. As a seat cushion in a vehicle seat device having such a configuration, for example, Japanese Utility Model Laid-Open No. 4-45445
As disclosed in Japanese Patent Application Laid-Open Publication No. H11-163, a main body portion made of a urethane-based elastic material, a plurality of first spring members that support the main body portion by contacting the lower surface thereof, and a plurality of first spring members are arranged on a floor portion in a vehicle compartment forming portion. There has been proposed a configuration including a plurality of second spring members that are disposed on a fixed portion to be supported and that support the main body portion and the plurality of first spring members. In this seat cushion, a seat pressure receiving portion is formed by a main body made of a urethane-based elastic material and a plurality of first spring members supporting the main body.

ることになる。According to the seat cushion proposed as described above, the amount of deflection of the seat pressure receiving portion and the plurality of second spring members supporting the seat pressure receiving portion is appropriately set, so that the floor in the vehicle compartment forming portion is formed. Vibrations transmitted to the seat cushion through the portion, particularly vibrations at relatively high frequencies, can be effectively absorbed. Therefore, the vibration transmitted to the seat cushion through the floor portion in the cabin forming portion, particularly, the transmission of the vibration having a relatively high frequency to the seated occupant is suppressed, and the so-called “high-frequency ruggedness” is felt by the occupant. The feeling is reduced.

いう不都合が生じるのである。However, like the seat cushion proposed in the prior art, the seat pressure receiving portion is supported by the spring member with respect to the fixed portion, and the floor portion in the vehicle compartment forming portion is formed. In a seat cushion in a vehicle seat device having a configuration capable of effectively absorbing vibration transmitted through the vehicle, the amount of lateral deflection is relatively large due to its structure. The lateral swing that occurs when the vehicle is in a turning state, etc., has a small resistance and cannot be effectively suppressed, and lacks stability with respect to the support of a seated occupant. There is a risk of becoming. In other words, the seat cushion has a configuration in which the seat pressure receiving portion is supported by the spring member with respect to the fixed portion, and is configured to be able to effectively absorb the vibration transmitted through the floor portion in the vehicle interior forming portion. However, there is an inconvenience that the demand for making the seated occupant feel good sitting comfort can be satisfied, but the demand for stably supporting the seated occupant cannot be sufficiently satisfied.

Absorbing the seated occupant can make the seated occupant feel good sitting comfort, and also appropriately restrains the lateral swing that occurs when the vehicle is turning, etc., and stabilizes the seated occupant. It is an object of the present invention to provide a vehicle seat device that can be supported.

きることになる。Then, when the vehicle is in a normal running state, for example, mainly in straight running, the elastic member elevating means 2
0 is a state in which the movable support member 21 assumes a lower position, and the lower elastic member 15 placed on the movable support member 21 assumes a position separated from the seat pressure receiving portion as shown in FIG. Put in. As a result, the seat pressure receiving portion constituted by the upper elastic member 10 and the second spring member 13 is supported by the first spring member 6 and is separated from the lower elastic member 15, so that the vehicle Vibration transmitted to the seat cushion 1 through the cabin forming portion as the vehicle travels is appropriately absorbed by the seat cushion 1, and transmission to the seated occupant is effectively suppressed, and the seated occupant is effectively suppressed. Can feel good sitting comfort.

It is moved to the upper position, and the lower elastic member 15 placed on the lower elastic member 15 is brought into contact with the seat pressure receiving portion from below. Thereby, as shown in FIG. 5, the lower elastic member 15
Four annular members 1 in which the plurality of engagement recesses 18 are attached to a plurality of second spring members 13 forming a seat pressure receiving portion.
In a state of being engaged with the respective seats 4, they come into contact with the seat pressure receiving portion supported by the first spring member 6 from below. As a result, the amount of deflection in the lateral direction is made relatively small by the action of the lower elastic member 15 in which the seat cushion 1 is engaged with the seat pressure receiving portion. Is appropriately suppressed, and the lateral displacement of the seat cushion 1 is effectively suppressed. Therefore, the seated occupant is stably supported.

クッションの横方向への変位が効果的に抑制される。As is apparent from the above description, the vehicle seat apparatus according to the present invention is capable of vertical movement.
However, the state in which the elastic member is brought into contact with the seat pressure receiving portion from the lower side by the operation of the elastic member lifting / lowering means whose lateral movement is restricted, and the elastic member moves from the seat pressure receiving portion to the lower side thereof. Are separated from each other.
You. Then , in a state where the elastic member is separated from the seat pressure receiving portion below the seat pressure receiving portion, the seat pressure receiving portion is placed in a state supported by the spring member arranged on the fixed portion. Therefore, the vibration transmitted to the seat cushion through the cabin forming portion as the vehicle travels,
Are adequately absorbed in the seat cushion, transmitted to the occupant Ru is effectively suppressed. In a state in which the elastic member comes into contact with the seat pressure receiving portion from below, the seat pressure receiving member is supported by the spring member and the elastic member disposed on the fixed portion, and , Elastic member
The engagement member provided on the seat pressure receiving portion is engaged.
Would be engaged in part, moreover, the elastic member is moved up and down in
Elastic member elevating hands that are allowed but whose lateral movement is restricted
It means that the position regulated by the stage, the seat cushion, is assumed to amount of deflection in the transverse direction is relatively small by the abutment of action of the elastic member from the lower side to the seat pressure receiving portion, whereby the vehicle Lateral rocking that occurs when the vehicle is in a cornering state is appropriately suppressed, and lateral displacement of the seat cushion is effectively suppressed.
