When the lock release lever 26 is released, the front seat 3 can be fixed to a desired position of the rail body 12 of the fixing member 11. ing.

  Here, as shown in FIG. 5, the unlocking rod 24 of the unlocking lever 26 includes a torsion spring 27 for biasing the grip 25 of the unlocking lever 26 downward, and the torsion spring 27 locks it. A locking portion (not shown) linked to the release rod 24 is locked to the rail body 12.

An air conditioning duct 30 is disposed on the front floor 1 below the lock release lever 26. This air-conditioning duct 30 supplies conditioned air to the rear seat occupant from the vicinity of the floor tunnel 2 in the foot space 4 through the inclined portion 5 of the front floor 1 and the installation portion 6 of the front seat 3 from within an instrument panel (not shown). It is.
Specifically, the air-conditioning duct 30 includes an air-conditioning air inlet 31 directed upward at the front end, extends rearward along the floor tunnel 2, and extends from the floor tunnel 2 at the inclined portion 5 of the front floor 1. It bends obliquely toward the outside of the passenger compartment so as to leave, and at the installation portion 6 of the front seat 3, it extends rearward along the rail body 12, and the rear end portion is cut obliquely outward toward the rear seat occupant. The blower outlet 32 is formed as an opening.

  The air conditioning duct 30 includes a mounting piece 33 extending toward the center in the vehicle width direction at the rear end, and the mounting piece 33 is fixed to the installation portion 6 of the front seat 3 with a clip 34. Further, an attachment piece 33 ′ extending toward the center in the vehicle width direction is formed in the vicinity of the front end portion of the air conditioning duct 30 and is fixed to the front floor 1 with a clip 34 ′. In addition, the air-conditioning duct 30 is integrally connected with the front part and the rear part by the connection part 35 provided in the center part in the front-back direction.

  As shown in FIGS. 4 and 6, a claw portion 37 that rises upward is formed on the side wall 36 of the air conditioning duct 30 near the floor tunnel 2 and on the side portion of the grip portion 25 of the lock release lever 26. ing. The claw portion 37 protrudes upward from a bulging portion 38 formed on the side wall 36 on the front side of the connection portion 35 of the air conditioning duct 30. The claw portion 37 includes a downward inclined portion 39 that continues to the upper surface of the bulging portion 38 and descends obliquely downward toward the floor tunnel 2, and an upward inclined portion 40 that continues to the downward inclined portion 39 and then rises toward the tip. Further, it is formed so as to descend downward from the top 41 of the rising inclined portion 40.

  Corresponding to the claw portion 37, a fitting portion 42 that fits the claw portion 37 of the air conditioning duct 30 is formed on the leg portion 13 a on the front side of the fixing member 11. Specifically, the fitting portion 42 is formed in a portion sandwiched between the cutout portions 43 on both sides of a part of the flange portion 15 on the side opposite to the floor tunnel 2 in the flange portion 15 of the leg portion 13a. After extending in the direction, an extending portion 44 extending diagonally downward so as to correspond to the rising inclined portion 40 of the claw portion 37 is provided.

  According to the above-described embodiment, the air conditioning duct 30 receives a load from the front side as the front floor 1 is deformed at the time of a vehicle frontal collision, gets on the inclined portion 5 of the front floor 1 and moves away from the front floor 1 in an upward direction. The air conditioning duct 30 fixed to the front floor 1 is prevented from being lifted upward in the vicinity of the lock release lever 26 even if the force is received.

  That is, when the air conditioning duct 30 receives an upward force, the claw portion 37 of the air conditioning duct 30 is fitted into the fitting portion 42 of the leg portion 13a attached to the front side of the rail body 12 of the slide rail 7. Therefore, the air conditioning duct 30 cannot be displaced upward at the position of the claw portion 37. Therefore, it is possible to prevent the lock release lever 26 located above the claw portion 37 from being operated upward. Here, since the nail | claw part 37 is formed in the bulging part 38 of the air-conditioning duct 30, it can prevent that a load acts on the nail | claw part 37 intensively, and receives the load also in the bulging part 38. This is advantageous in that

In addition, the claw portion 37 formed integrally with the air conditioning duct 30 and the fitting portion 42 provided integrally with a part of the flange portion 15 formed on the leg portion 13a of the rail body 12 are provided for fixing. Since measures can be taken without using a special member separately, there is an advantage that the number of parts can be reduced and the number of assembling steps can be reduced as compared with the case where separate parts are provided.
In particular, in this embodiment, since the fitting part 42 is provided in the leg part 13a which is a high-strength member for fixing the rail body 12 to the front floor 1, the reliability is also improved.

Further, since the upward inclined portion 40 of the claw portion 37 formed in the air conditioning duct 30 and the extended portion 44 of the fitting portion 42 formed in the leg portion 13a are brought into contact with each other on the inclined surface and are fitted to each other, a vehicle front collision Sometimes, the upward deformation of the air conditioning duct 30 can be suppressed, and the lateral displacement of the vehicle body can also be suppressed.
The present invention is not limited to the above-described embodiment. For example, the front seat on the driver's seat side has been described as an example. However, the present invention can also be applied to the case where the air conditioning duct 30 is provided on the front seat on the passenger seat side.
