It is formed slightly wider than the dimension T2 (see FIG. 13) obtained by adding the thickness dimension of the lap belt 20B to the height direction dimension. In addition, the width dimension W2 of the height direction one end part (end part by the side of the flange part 58D) of the bezel 58 is set larger than said width dimension W1.

  Next, the operation and effect of this embodiment will be described.

  In the vehicle seat device 10 configured as described above, the side support portion 16B on the right side (the vehicle width direction outer side) of the seat cushion 16 has an internal space 44, and one end in the longitudinal direction of the lap belt 20B is in the internal space 44. The webbing take-up device 36 with the portion locked is accommodated. Therefore, the vehicle seat device 10 wraps even a vehicle in which the mounting space for the webbing retractor 36 cannot be secured on the outer side surface of the seat cushion 16 in the width direction (such as between the vehicle body side portion 22A and the seat cushion 16). The belt 20B can be taken up by the webbing take-up device 36.

  Moreover, an opening 50 communicating with the internal space 44 is formed in a portion (inclined surface S) facing the seated occupant P in the side support portion 16B on one side in the width direction, and the bezel attached to the opening 50 is formed. 58 is formed with a webbing insertion hole 58A through which the intermediate portion in the longitudinal direction of the lap belt 20B is inserted. As a result, the lap belt 20B whose one end in the longitudinal direction is locked to the webbing take-up device 36 and whose other end in the longitudinal direction is locked to the buckle 32 on the other side in the width direction of the seat cushion is seated on the seat occupant P. Therefore, the restraint of the seated occupant by the lap belt 20B can be improved.

  When the webbing take-up device 36 is attached to the side surface of the seat cushion 16 or when the lap belt 20B is pulled out from the opening formed on the side surface of the seat cushion 16, the webbing take-up device 36 is used. Since a part of the lap belt 20B between the occupant P and the seated occupant P is wound around the top of the side support portion 16B, the restraining force of the lap belt 20B slightly changes as the side support portion 16B (cushion pad 38) bends. However, the vehicle seat device 10 is preferable because it is not affected by the bending of the side support portion 16B.

  In the vehicle seat device 10, when the bezel 58 is attached to the opening 50 from the outside of the seat cushion 16, the locking claws 58 </ b> B and 58 </ b> C provided on the bezel 58 are used as the first opening of the cushion pan 40. It hooks on the locking projections 40D and 40E formed on the hole edge of 40A. Thereby, since the bezel 58 can be locked to the cushion pan 40, that is, the seat cushion 16, it is possible to prevent the bezel 58 from being unnecessarily detached from the opening 50. In addition, the work of assembling the bezel 58 to the seat cushion 16 is easy.

  Further, in the vehicle seat device 10, the peripheral edge portion of the first opening portion 40 </ b> A formed in the cushion pan 40 has a protruding portion 40 </ b> B protruding inward of the second opening portion 38 </ b> A formed in the cushion pad 38. The peripheral edge of the third opening 42A of the seat skin 42 is sandwiched between the protrusion 40B and the flange 58D of the bezel 58. That is, since the cushion pad 38 is not interposed between the flange portion 58D of the bezel 58 and the protruding portion 40B (cushion pan 40), the bezel 58 is locked to the cushion pan 40 by the deformation of the cushion pad 38 ( It is possible to prevent the locking claws 58B and 58C from being hooked on the locking protrusions 40D and 40E. Therefore, it is possible to prevent the bezel 58 from being unnecessarily detached from the opening 50.

  Further, in the vehicle seat device 10, when the bezel 58 is attached to the opening 50, the pair of locking claws 58 </ b> B and 58 </ b> C protruding to the opposite sides via the webbing insertion hole 58 </ b> A are provided with the cushion pan 40. After being hit by the locking projections 40D and 40E and being bent, they are hooked on the lower edges of the locking projections 40D and 40E. At this time, the pair of locking claws 58B and 58C bend so as to narrow the webbing insertion hole 58A, but in the vehicle seat device 10, the pair of locking claws 58B and 58C are in the height direction of the bezel 58, that is, Since the bezel 58 is disposed so as to be displaced in the mounting direction of the bezel 58 to the opening 50 (the direction of arrow A in FIG. 7), the pair of locking claws 58B and 58C bend alternately. Therefore, it is not necessary to enlarge the width dimension W3 (see FIG. 12) of the webbing insertion hole 58A in order to secure a space for the pair of locking claws 58B and 58C to bend simultaneously. Accordingly, the width dimension W3 of the webbing insertion hole 58A can be set small, so that dust or the like can enter the internal space 44 from the gap between the inner peripheral portion of the webbing insertion hole 58A and the lap belt 20B. Can be suppressed.

  Further, in the vehicle seat device 10, since the bezel 58 has the flange portion 58 </ b> D that engages with the peripheral edge portion of the opening 50, the bezel 58 is inserted into the opening 50 in its mounted posture. In this case, the flange portion 58D is obstructed and cannot be inserted, but the bezel 58 is inclined so that the height direction of the bezel 58 is along the width direction of the opening 50 as shown in FIG. The bezel 58 can be inserted through the opening 50 by tilting the locking claw 58B having the shorter leg toward the locking claw 58C having the longer leg). Therefore, even after the webbing retractor 36 in which the lap belt 20B and the bezel 58 are assembled is accommodated in the inner space 44 of the seat cushion 16, the lap belt 20B and the bezel 58 are attached to the seat cushion 16 through the opening 50. The bezel 58 can be pulled out to the outside and the bezel 58 can be attached to the opening 50 from the outside of the seat cushion 16. Thereby, the manufacturing operation of the vehicle seat device 10 can be facilitated. Moreover, since the width dimension of the opening part 50 can be set small, the width direction W2 of the bezel 58 can be made small as a result, and the bezel 58 can be reduced in size. Accordingly, it is possible to suppress the bezel 58 attached to the opening 50 from interfering with the seated occupant P.

  Further, in the vehicle seat device 10, the cloth member 52 sewed on the peripheral edge of the third opening 42 </ b> A of the seat skin 42 is wound around the rib 40 </ b> C provided on the cushion pan 40, and the metal clip 54 and the resin Since it is the structure latched by the clip 56, the peripheral part of the 3rd opening part 42A can be latched to the cushion pan 40 easily. Moreover, since the resin clip 56 is attached to the outside of the metal clip 54, the cloth member 52 can be firmly locked to the rib 40C by the metal clip 54, and the locking force of the metal clip 54 can be increased by the resin clip 56. The contact between the metal clip 54 and the lap belt 20B can be prevented while increasing.
