  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

  The effects of the present invention are as follows.

The invention of claim 1 includes a left and right seat bracket that extends in the front-rear direction of the vehicle body and is supported on the vehicle compartment floor panel side, and a seat cushion frame supported by the left and right seat brackets. The frame extends in the front-rear direction and is supported by fasteners on the respective seat brackets by the left and right side frames, and extends in the width direction of the vehicle body, before the left and right side frames are joined to each other, In a vehicle seat device comprising a rear frame,
An engaging portion is formed at each end portion of at least one of the front and rear frames, and the other engaging portions that face each of the engaging portions from the outside in the width direction of the vehicle body are described above. When the left and right seat brackets are deformed so as to approach each other in the width direction of the vehicle body by an external force from the outside of the seat cushion frame formed on each seat bracket, the engaging portion and the other engaging portion Are engaged with each other.

  For this reason, when an external force is applied to the seat cushion frame from the outside when the vehicle crashes into the vehicle, the left and right seat brackets supporting the seat cushion frame may be deformed so as to approach each other. In this case, the engaging portion and the other engaging portion are engaged with each other, and the one frame works to stretch the left and right seat brackets through the engaging portions, thereby The above deformation of the left and right seat brackets is prevented.

  Therefore, the external force is firmly supported on the passenger compartment floor panel side through the seat cushion and the left and right seat brackets, which are prevented from being deformed as described above. Deformation is prevented.

  And prevention of a deformation | transformation of the left and right seat bracket at the time of the above-mentioned side collision is achieved by utilization of said one frame of the said seat cushion frame, without providing a separate reinforcement material like the prior art. Therefore, excessive deformation of the seat device at the time of a side collision can be prevented by using the seat cushion frame with a simple configuration and avoiding excessive mass.

  The invention according to claim 2 is that at least the engaging portion of the inner end portion of the engaging portions formed at the inner and outer end portions in the width direction of the vehicle body of the one frame is at the lower end portion of the inner end portion. The lower end portion of the inner end portion is positioned lower than the lower end portion of the midway portion in the width direction of the vehicle body of the one frame.

  Therefore, as described above, when a side collision occurs, an external force is applied to the seat cushion frame from the outside, and the engagement portion and the other engagement portion engage with each other. When the frame works to stretch the left and right seat brackets, the one frame is given a compressive force in the longitudinal direction based on the external force, with the lower end portion of the inner end portion as an action point. Then, due to this compressive force, the one frame tends to bend so that the midway portion in the longitudinal direction has an upwardly convex arc shape.

  Therefore, the amount of external force applied to the inner seat bracket via the one frame from the outer seat bracket in the width direction of the vehicle body of the two seat brackets as much as one frame tends to bend as described above. Alleviated. For this reason, it is suppressed that the upper part side of the said inner side seat bracket inclines toward the inner side of a vehicle body.

  In addition, as described above, one of the frames tends to bend so as to form an upwardly convex arc shape based on the external force. For this reason, the inner end of the one frame is prevented from being displaced upward relative to the inner seat bracket due to the external force, so that the one frame is moved around its base with respect to the inner seat bracket. Giving a large bending moment is prevented, and tilting of the upper side of the inner seat bracket toward the inner side of the vehicle body is more reliably suppressed.

  Therefore, both the seat brackets are prevented from tilting inwardly of the vehicle body based on the external force, and the seat device is more reliably prevented from being greatly deformed.

  In addition, as described above, the lower end portion of the inner end portion of one frame of the seat cushion frame is positioned lower, and this inner end portion is the base side of the inner seat bracket that supports the seat cushion frame (vehicle compartment). Move closer to the floor panel. Therefore, the external force applied from the outer seat bracket to the inner seat bracket via the one frame does not give the large bending moment to the inner seat bracket, but by the base side of the inner seat bracket, It is supported more firmly and stably. As a result, the deformation of the seat device based on the external force is more reliably prevented.

  Further, the deformation prevention of the seat device described above is obtained by using one frame of the seat cushion frame as described above and by devising the shape of this one frame. Compared to simply increasing the vertical width of the one frame as a whole, deformation of the seat device can be prevented with a simple structure and while suppressing an increase in mass.

  3, 4, and 5, the left and right seat brackets 10, 10 have a width of the vehicle body 2 due to an external force F applied from the outer side to the seat cushion frame 24 of the seat device 7 in a side collision with the vehicle 1. When deforming to approach each other in the direction (L in FIG. 2 → L ′ in FIG. 5), each of the engaging portions 42 and each of the other engaging portions 43 are engaged with each other (FIG. 5). .

  For this reason, when an external force F is applied to the seat cushion frame 24 from the outside when the vehicle 1 collides with the vehicle 1, the left and right seat brackets 10 and 10 that support the seat cushion frame 24 are mutually connected.

As a result, the sheet device 7 is prevented from being excessively deformed during a side collision.

  Further, the deformation prevention of the left and right seat brackets 10 and 10 at the time of the above-described side collision is achieved by using the rear frame 30 of the seat cushion frame 24 without providing a separate reinforcing material as in the prior art. The Therefore, excessive deformation of the seat device 7 at the time of a side collision can be prevented by using the rear frame 30 of the seat cushion frame 24 with a simple configuration and avoiding excessive mass.

  FIG. 6 below shows Example 2, and FIG. 7 shows a reference example. The second embodiment and the reference example are common to the first embodiment in many respects in configuration and operational effects. Therefore, regarding these common items, common reference numerals are attached to the drawings, and redundant description thereof is omitted, and different points are mainly described. In addition, the configuration of each part in these embodiments may be variously combined in light of the object and operational effects of the present invention.

  In order to describe the present invention in more detail, Example 2 will be described with reference to FIG. 6 attached here. In this case, FIG. 7 will be described as a reference example.

  In FIG. 6, at least the engaging portion 42 of the inner end portion 30a among the engaging portions 42, 42 formed at the inner and outer end portions 30a, 30b in the width direction of the vehicle body 2 of the rear frame 30 is the inner side. It is formed in the lower end part of the edge part 30a, and the lower end part of this inner side edge part 30a is positioned lower than the lower end part of the middle part in the width direction of the vehicle body 2 of the rear frame 30.

  Here, as shown in the reference example of FIG. 7, it is assumed that the rear frame 30 extends linearly in the width direction of the vehicle body 2, and cross sections thereof have the same shape. In this case, the rigidity of the rear frame 30 increases with respect to the compressive force applied in the longitudinal direction.

  Here, as described above, at the time of a side collision, an external force F is applied to the seat cushion frame 24 from the outer side, and the engaging portion 42 and the other engaging portion 43 are engaged with each other. It is assumed that the rear frame 30 of the cushion frame 24 works to stretch the left and right seat brackets 10 and 10 '. Then, in this case, the external force F applied to the outer seat bracket 10 in the width direction of the vehicle body 2 through the seat cushion frame 24 among the both seat brackets 10 and 10 'is the rigidity described above. Is transmitted to the inner seat bracket 10 ′ through the rear frame 30 having a large height. Moreover, the inner seat bracket 10 'and the rear frame 30 inner end 30a are engaged with the engaging portion 42 and the other engaging portion 43 as described above. The inner seat bracket 10 ′ and the inner end 30 a of the rear frame 30 are prevented from relatively moving in the front-rear direction of the vehicle body 2, and are not intended to prevent relative movement in the vertical direction.

  Therefore, when the external force F applied to the outer seat bracket 10 is transmitted to the inner seat bracket 10 'as it is through the rigid rear frame 30 as in the above-described reference example, in FIG. As indicated by the alternate long and short dash line, the seat bracket 10 ′ begins to tilt toward the inner side of the vehicle body 2 at the upper side. As a result, as shown by a one-dot chain line in FIG. 7, the inner end 30a of the rear frame 30 tends to be displaced upward relative to the inner seat bracket 10 ′. Then, based on the external force F, a second moment applied to the inner seat bracket 10 ′ around the base via the rear frame 30 is increased, and the inner seat bracket 10 ′ is moved inward of the vehicle body 2. It tends to lean a lot. As a result, the outer seat bracket 10 tends to be greatly inclined toward the inner side of the vehicle body 2.

  That is, according to the above-described reference example of FIG. 7, both the seat brackets 10 and 10 ′ tend to tilt toward the inner side of the vehicle body 2 based on the external force F, as indicated by a dashed line in FIG. 7. As a result, the sheet device 7 may be greatly deformed.

  Therefore, as described above, at least the engaging portion 42 of the inner end portion 30a among the engaging portions 42 and 42 formed on the inner and outer end portions 30a and 30b in the width direction of the vehicle body 2 of the rear frame 30 is provided. The lower end portion of the inner end portion 30a is positioned lower than the lower end portion of the middle portion of the rear frame 30 in the width direction of the vehicle body 2 while being formed at the lower end portion of the inner end portion 30a.

  Therefore, as described above, an external force F is applied to the seat cushion frame 24 from the outer side in a side collision, and the engaging portion 42 and the other engaging portion 43 are engaged with each other. When the rear frame 30 of the cushion frame 24 works to stretch the left and right seat brackets 10 and 10 ', the rear frame 30 is longitudinal based on the lower end of the inner end 30a based on the external force F. A compressive force is applied in the direction. Then, due to this compressive force, as shown by the one-dot chain line in FIG. 6, the rear frame 30 tends to bend so that a midway portion in the longitudinal direction has an upward convex arc shape.

  Therefore, as the rear frame 30 tends to be bent as described above, the inner seat through the rear frame 30 from the outer seat bracket 10 in the width direction of the vehicle body 2 of the two seat brackets 10 and 10 '. The external force F applied to the bracket 10 'is alleviated. For this reason, the upper side of the inner seat bracket 10 ′ is prevented from tilting toward the inner side of the vehicle body 2.

  In addition, as described above, the rear frame 30 tends to bend based on the external force F so as to have an upwardly convex arc shape as indicated by a one-dot chain line in FIG. For this reason, the inner end portion 30a of the rear frame 30 is prevented from being displaced upward relative to the inner seat bracket 10 'by the external force F, whereby the rear frame 30 is prevented from being displaced to the inner seat bracket 10'. On the other hand, it is possible to prevent a large bending moment from being applied around the base portion, and to prevent the upper side of the inner seat bracket 10 ′ from tilting toward the inner side of the vehicle body 2 is more reliably suppressed.

  Therefore, based on the external force F, as exemplified by the one-dot chain line in FIG. 7, both the seat brackets 10, 10 ′ are prevented from tilting inward of the vehicle body 2, and the seat device 7 is greatly enlarged. Deformation is more reliably prevented.

  Further, as described above, the inner end 30a is positioned on the lower side of the inner end 30a of the rear frame 30 of the seat cushion frame 24 so that the inner end 30a supports the seat cushion frame 24. Closer to the base side (vehicle compartment floor panel 4 side). Therefore, the external force F applied from the outer seat bracket 10 to the inner seat bracket 10 'via the rear frame 30 does not give the above-mentioned large bending moment to the inner seat bracket 10'. It is more firmly and stably supported by the base side of the bracket 10 '. As a result, the deformation of the seat device 7 based on the external force F is more reliably prevented.

  Further, the deformation prevention of the seat device 7 described above is obtained by using the rear frame 30 of the seat cushion frame 24 as described above and by devising the shape of the rear frame 30. For example, it is possible to prevent deformation of the seat device 7 with a simple configuration and suppressing an increase in mass compared to simply increasing the vertical width of the rear frame 30 as a whole.

  Although the above is based on the illustrated example, in addition to or instead of the engaging portion 42 and the other engaging portion 43, an engaging portion 42 is formed on the front frame 29, and this engaging portion The other engaging portion 43 may be formed on the bracket panel 21 of the seat bracket 10 so as to correspond to 42. One of the engaging portion 42 and the other engaging portion 43 is a protrusion that protrudes in the width direction of the vehicle body 2, and the other is a through-hole that penetrates in the width direction of the vehicle body 2. A concave portion that is recessed in the width direction may be used. In this way, the engagement portions 42 and 43 are engaged with each other in the front-rear direction of the vehicle body 2 by the engagement between the engagement portion 42 and the other engagement portion 43. The movement is blocked and the relative movement of the vehicle body 2 in the vertical direction is also blocked.

  Further, in FIG. 6 according to the second embodiment, the lower end portion of the outer end portion 30b of the rear frame 30 is the lower end portion of the midway portion in the width direction of the vehicle body 2 of the rear frame 30 as in the reference example of FIG. You may make it the same height.
