- the inflator 50 has a narrow plate-like retainer 75 (see FIG. 2) as a mounting seat, and is attached to the lower outer peripheral surface of the inner tube 36 via a rear end side mounting bracket 76 that is formed narrow in side view. It is fixed (the fixing structure will be described in the second and third embodiments described later).
- a frontal collision occurs (or when a frontal collision is predicted), it is detected by a collision detection means (not shown). Is detected and output to the airbag ECU.
- the driver side airbag device is actuated to inflate the driver seat airbag 66 on the steering wheel 34 and the column-attached knee airbag device 10. Is also activated. That is, a predetermined current is applied to the inflator 50 of the column-attached knee airbag device 10 to activate the inflator 50.
- gas from the inflator 50 is generated and supplied to the knee airbag 52 stored in a folded state, and the knee airbag 52 is inflated.
- the column lower cover 22 breaks along a tear line (not shown) set in the column lower cover 22, and the airbag door 60 is expanded.
- the knee airbag 52 is inflated and deployed below and to the side of the steering column 12, and the left and right side portions 52B interposed between the instrument panel 14 and both knees of the passengers Is received and protected.
- the air bag module 64 of the knee airbag device 10 with column is placed in the limited installation space 74 formed between them. Inflated and deployed The knee can be restrained.
- the airbag module 64 by disposing the airbag module 64 at this position, the distance between the steering column 12 and the occupant's knee in a side view is substantially the shortest distance, so that the capacity of the knee airbag 52 is greatly increased. Can be reduced.
- the “occupant's knee” here refers to the “kneecap” (the same shall apply hereinafter). Accordingly, the folded U airbag 52 is also made very compact, and the inflator 50 can be made smaller. As a result, a very compact airbag module 64 is obtained, and two interfering objects, the lower part 70A of the main body 70 of the combination switch 68 and the lower part 48A of the housing 48, are separated by a predetermined distance in the axial direction of the steering column 12. Even when there is a restriction that the air bag modules 64 are arranged apart from each other, the air bag module 64 can be installed.
- the occupant's knees can be quickly restrained even with respect to the steering column structure in which there are a plurality of interferences below the rear end side of the steering column 12.
- multiple interfering objects are a combination of the lower part 70A of the main body part 70 of the combination switch 68 and the lower part 48A of the housing 48 for fixing the steering column 12 to the steering support 42, it is possible to respond flexibly. it can.
- the rigid inflator 50 is arranged so as to be offset (offset) toward the main body 70 side of the combination switch 68, so that the load of the arrow F is applied to the steering column 12 at the time of a frontal collision. Even if the inner tube 36 moves into the outer tube 38 within the predetermined stroke range, the inflator 50 and the outer tube 38 do not interfere with each other. Therefore, the contraction operation of the column tube 26 is performed smoothly, and the energy absorption performance of the steering column 12 can be maintained well.
- the module case 54 is made of cloth. Therefore, when the column tube 26 is contracted, the front end corner portion 64A of the airbag module 64 (see Fig. 2).
- the module case 54 and the knee airbag 52 are flexibly deformed even if there is a slight interference with the lower part 48A of the housing 48. Therefore, the movement stroke (energy absorption stroke) of the column tube 26 is not reduced at all. That is, it is possible to secure a predetermined movement stroke (energy absorption stroke) of the column tube 26.
- This effect is also the result of 68 combination switches.
- the distance between the lower part 70A of the body part 70 and the lower part 48A of the housing 48 is shorter and the installation space 74 force is narrow in the axial direction of the column. The effect is that it can be installed in a compact space.
- the airbag module 64 is fixed to the adjacent portion of the lower portion 70A of the main body 70 of the combination switch 68 in the inner tube 36 by using the rear end side mounting bracket 76 having a narrow width in a side view, In addition to the offset arrangement of the inflator 50, the attachment point of the air bag module 64 is also set at the position adjacent to the lower part 70A of the main body 70 of the combination switch 68, and the possibility of hindering the contraction operation of the column tube 26 is further eliminated. .
- the second embodiment is characterized in that the front end corner portion 64A of the airbag module 64 is slidably fixed to the lower portion 48A of the housing 48.
- an L-shaped attachment member 80 is set inside the front end corner of the fabric module case 54 in a side view, and the same is applied to the inside of the rear end corner of the module case 54.
- a mounting member 82 having a shape is set.
- the front end mounting member 80 is fixed to the rear end portion of the front mounting bracket 84 formed in a substantially Z shape in a side view with a bolt 86 and a nut 88.
- the front end portion of the front mounting bracket 84 is fixed to a bottom wall portion 90 (see FIG. 4) constituting a part of the lower portion 48A of the housing 48 by fixing means such as bolts and nuts (not shown).

- the mounting member 80 also moves to the column rear end side by the same stroke as the moving stroke of the lower part 48A of the housing 48. Since the module case 54 is made of cloth and the knee airbag 52 is also made of a flexible material, the relative movement of the lower portion 48A of the housing 48 can be absorbed. Therefore, the contraction operation of the column tube 26 is performed smoothly.
