本考案は、車両に搭載されるシート装置、特に
そのシートクツシヨンのシートロツク機構及び強
制ロツク機構の改良に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a seat device mounted on a vehicle, and particularly to an improvement of a seat lock mechanism and a forced lock mechanism of the seat cushion.
（従来の技術）

The one described in JP-A-110733 is known.

３８を含む機構）とが設定されている。 This conventional seat device has a seat lock mechanism (seat cushion side striker 29 and a locking member 31 on the vehicle floor side), and a forced locking mechanism (seat cushion) that locks the seat cushion to the vehicle floor by utilizing the forward displacement of the seat cushion when a large load is input from the seat belt to the seat member. A mechanism including an engagement bolt 30 on the side of the vehicle body and a catch plate 38 on the side of the vehicle body floor is set.
（考案が解決しようとする問題点）
しかしながら、従来のシート装置にあつては、
シートロツク機構と強制ロツク機構とが別々に設

てしまうという問題点があつた。(Problems to be solved by the invention) However, in the case of conventional seat devices,
Since the seat lock mechanism and forced lock mechanism are set separately, a large number of parts are required to be installed between the seat cushion and the vehicle floor, which is disadvantageous in terms of installation man-hours and costs. In addition, the number of protruding members and holes from the back side of the seat cushion and the floor surface of the vehicle body increases, resulting in a problem that the seat looks unsightly or becomes an obstacle when the seat is flipped up.

足することが出来ない。 Therefore, there is a proposal to focus on the fact that both mechanisms are locking mechanisms and to share the engaging parts and set them at the same position, but simply combining both mechanisms would not allow for smooth engagement and disengagement with a light operating force. The required performance of the seat lock mechanism is to obtain the function, and there is no interference with the seat lock mechanism until a large load is input that causes the seat cushion to move forward, and the lock is reliably activated when this large load is input. It is not possible to simultaneously satisfy the required performance of a forced locking mechanism such as durability.

た。(Means for Solving the Problems) The present invention was made with the purpose of solving the above-mentioned problems and issues. a seat lock mechanism that engages and disengages the seat cushion from the vehicle body; and a forced lock mechanism that locks the seat cushion to the vehicle body by utilizing forward displacement of the seat cushion when a large load is input from the seat belt to the seat member. In the seat device, a dual-purpose locking mechanism that serves both as the seat locking mechanism and a forced locking mechanism is supported by the seat member, and the dual-purpose locking mechanism includes a lockshaft that can be rotated by an external operating force, and a lockshaft that can be rotated by an external operating force. A striker that is fixed and has two vertical members that closely face each other and a horizontal member that connects the vertical members, a vehicle body hook that can be engaged with the horizontal member of the striker, and a state in which the seat cushion is ready for seating. a biasing means for rotationally biasing the lockshaft in a direction in which the striker engages with the vehicle body hook; and a lock hole opened in the seat member to allow the vehicle body hook to pass therethrough and having a width narrower than that of the striker. The lockshaft is configured such that when the seat cushion is displaced forward with respect to the vehicle body due to a large load input to the seat member, the horizontal member of the striker engaged with the vehicle body hook engages around the lock hole of the seat member. The means is characterized in that it is formed to be rigid enough to deform until it comes into contact with the part.

る。(Function) When the seat cushion flips up, when the lockshaft is rotated by an external operating force, the striker fixed to the lockshaft rotates in the disengagement direction, releasing the engagement state with the vehicle body hook. is,
The seat cushion can be flipped up in the center of the pivot point to stand up; conversely, when the seat cushion is rotated from the upright position to its original position, the vehicle body hook and striker are engaged, and the seat cushion is raised. is engaged with the vehicle body. In this state, you can sit down.

バのロツク穴の周部とは、係合していない。 In this normal seating ready state (other than when a large load is input), the vehicle body hook is inserted into the lock hole of the seat member, and the lockshaft is rotated by the biasing means to engage the striker fixed to the lockshaft. , the seat lock is maintained in an engaged state with the vehicle body hook, and rotation of the seat lock is restricted. Note that at this time, the vehicle body hook and the periphery of the lock hole of the seat member are not engaged with each other.

ストライカを介して車体フツクにより強制ロツク
され、入力荷重を車体で受ける。 Furthermore, when a large load is input from the seat belt to the seat member, which causes the seat cushion to displace forward relative to the vehicle body, the seat member is first displaced relative to the vehicle body, and at this time, the vehicle body hook and striker are rotated by the biasing means. Since the engaged state is maintained due to the dynamic bias, the lockshaft bends and deforms as the seat member is displaced. Furthermore, as the displacement of the seat member progresses (at this time, the bending deformation of the lockshaft also progresses), the striker engages with the periphery of the lock hole in the seat member, and the seat member is forcibly locked by the car body hook via the striker, causing the input The load is received by the vehicle body.
この強制ロツク作動時には、ロツク穴がストラ
イカより狭幅に設定されている為、ストライカに
係合している車体フツクがシートメンバから外れ
ることがなく、確実にロツク作動がなされる。 During this forced locking operation, since the locking hole is set narrower than the striker, the vehicle body hook engaged with the striker does not come off from the seat member, and the locking operation is reliably performed.
そして、車体フツクがストライカの近接対向す

車体フツクの曲げ変形が規制され、ほぼ剪断方向
のみの入力となることで、車体フツクがシートベ
ルト方向に曲げられてストライカより外れるとい
うことがない。 Since the car body hook is sandwiched between the two closely opposing vertical members of the striker, the bending deformation of the car body hook is restricted by these vertical members, and the input is almost only in the shear direction, so that the car body hook is connected to the seatbelt. There is no chance of it being bent in any direction and coming off the striker.

となる。 To return the seat device S to its original state, first rotate the seat bag 3 to its original upright position, and then rotate the seat cushion 2 in its upright position to its original position. After the striker 15 in contact with the spring 22 rotates against the spring 22, when it comes to the position of the engaging portion 16a, the vehicle body hook 16 and the striker 15 are engaged by the biasing force of the spring 22, and the seat cushion 2 is engaged with the vehicle body. In this state, the seat becomes a seat that can be sat on.

When a large load is input to the seat member 10 and the seat cushion 2 is displaced forward with respect to the vehicle body floor 1, the vehicle body hook 16 and the striker 15 are first maintained in an engaged state by the biasing force of the spring 22. seat member 10.
As the lockshaft 14 supported by the seat member 10 bends and deforms in accordance with the forward displacement of , the striker 15 engages with the member engaging portion 10a around the lock hole 17, and the seat member 10 engages with the vehicle body hook 16 via the striker 15.
The input load is forcibly locked by the vehicle body floor 1.

When a large load is input to the horizontal member 1 of the striker 15
5b is the seat member 1 around the lock hole 17
Since the striker 15 is formed to be bendable and deformable until it engages with the vehicle body hook 16
It does not disengage while being engaged with, and furthermore,
Since the lock hole 17 is set narrower than the striker 15, the vehicle body hook 16 engaged with the striker 15 does not come off from the seat member 10 when the forced lock is activated, and reliable forced lock operation can be guaranteed.

Since it is formed so that it can be bent and deformed until it is engaged, the striker will not separate from the car body hook while remaining engaged.Furthermore, since the lock hole is set narrower than the striker, it will not touch the striker when the forced lock is activated. The engaged car body hook does not come off the seat member,
Reliable forced lock operation can be guaranteed.
