Further, the adjustment lever 30 is rotated about the fixed shaft 28 downward (in the direction of arrow C in FIG. 1), so that the steering column 13 can be rotated in the vehicle vertical direction with respect to the holding frame 22 (unlocked). Status). On the other hand, when the adjustment lever 30 is rotated about the fixed shaft 28 upward (in the direction of arrow D in FIG. 1), the steering column 13 stops rotating with respect to the holding frame 22 (locked state). The steering column 13 is inclined in a direction toward the upper side as it goes toward the rear side of the vehicle.

  Accordingly, the steering column 13 can be tilted by moving the adjustment lever 30 in the direction of arrow C, and the steering column 13 can be fixed at a predetermined position by moving the adjustment lever 30 in the direction of arrow D. Yes.

  A steering shaft 40 is inserted through the central axis portion of the steering column 13, and the steering shaft 40 can rotate around the axis with respect to the steering column 13 and is prevented from moving in the axial direction. Further, an end portion 40A on the vehicle front side of the steering shaft 40 protrudes from the steering column 13 and is connected to a steering gear mechanism 42 on the vehicle body side. On the other hand, a steering wheel 44 is supported on an end 40B of the steering shaft 40 on the vehicle rear side, and the steering wheel 44 faces the driver.

The side end portion 40B is fixed at the rotation center portion of the steering wheel 44 (the center portion of the rim portion 46). Thus, when the steering wheel 44 is rotated, the steering shaft 40 is rotated around the axis, and the vehicle is steered.

  FIG. 3 is an enlarged cross-sectional view taken along line 3-3 in FIG. In FIG. 3, illustration of the inside of the cross section of the steering column 13 is omitted.

  As shown in FIG. 3, a knee airbag device 58 as a knee protection airbag device is attached to a mounting portion 16 </ b> B provided at the lower end portion of the support cylinder 16 in the steering column 13 via a knee airbag mounting bracket 54. It has been. Further, an attachment portion 54A formed at the center in the vehicle width direction of the knee airbag attachment bracket 54 is fixed to the attachment portion 16B of the support cylinder 16 by a fastening member 55 such as a bolt. Note that knee airbag support portions 54B are formed on both outer sides in the vehicle width direction of the attachment portion 54A of the knee airbag mounting bracket 54, and these knee airbag support portions 54B are module cases of the knee airbag device 58. 62 is fixed.

  As shown in FIG. 2, the knee airbag device 58 has a knee airbag 60 as a knee protection airbag, and the knee airbag 60 is seated in the driver's seat at the time of a vehicle collision (at the time of a vehicle front collision). The vehicle is inflated and deployed from below the vehicle along the lower part 10A of the instrument panel 10 so as to restrain the knee 82A of the driver 82.

  When the knee airbag 60 is deployed, when the vehicle collides (when the vehicle collides), in addition to the case where the vehicle actually collides with another vehicle (crash), the collision occurs before colliding with the other vehicle. Including the case of predicting (pre-crash).

  As shown in FIG. 1, the knee airbag device 58 houses a knee airbag 60 and an inflator 64 that supplies inflation gas to the knee airbag 60 in a module case 62. The opening 62A of the module case 62 is covered with an airbag cover 66 that is deployed by an inflating force. The inflator 64 is controlled by an airbag control device (not shown) and operates when a frontal collision of the vehicle is detected, and a large amount of gas is ejected and supplied into the knee airbag 60. .

  An airbag opening 68 for accommodating the knee airbag device 58 is formed in the lower part 10A of the instrument panel 10, and the airbag opening 68 has a rectangular shape whose longitudinal direction is the vehicle width direction. It has become. The vertical opening width W1 of the airbag opening 68 along the instrument panel 10 is such that when the knee airbag device 58 is tilted together with the steering column 13, the peripheral edge of the airbag opening 68 is knee-tight. The size is set so as not to interfere with the airbag device 58.

  An upper portion 66A of the airbag airbag cover 66 overlaps with the passenger compartment side of the upper peripheral edge portion 10B of the airbag opening 68 in the instrument panel 10, and a lower portion 66B of the airbag airbag cover 66 in the instrument panel 10 It overlaps with the passenger compartment side of the lower peripheral edge portion 10C of the airbag opening 68. The vertical width W2 of the airbag airbag cover 66 along the instrument panel 10 is always the width that covers the airbag opening 68 even when the knee airbag device 58 is tilted together with the steering column 13. Is set. Therefore, even if the steering wheel 44 is tilted in the vehicle vertical direction, the airbag opening 68 is not exposed.

  The cross-sectional shape of the lower portion 10A of the instrument panel 10 viewed from the vehicle width direction is an arc shape, and the cross-sectional shape of the airbag airbag cover 66 viewed from the vehicle width direction is also an arc shape. The cross-sectional shape of the lower portion 10 </ b> A of the instrument panel 10 as viewed from the vehicle width direction is an arc shape that substantially follows the movement locus of the airbag airbag cover 66 that accompanies the tilting operation of the steering column 13. That is, the cross-sectional shape viewed from the vehicle width direction of the lower portion 10 </ b> A of the instrument panel 10 is a cross-sectional shape close to an arc shape centering on the rotation shaft 18.

  Therefore, as the steering column 13 is tilted, the airbag airbag cover 66 can smoothly move in the vehicle vertical direction along the lower portion 10A of the instrument panel 10.

  A folded portion 66C is formed from the upper end edge of the upper portion 66A of the airbag airbag cover 66 toward the lower front side of the vehicle, and the folded portion 66C hits the lower portion 10A of the instrument panel 10 by elastic force. Similarly, a folded portion 66D is formed from the lower end edge of the lower portion 66B of the airbag airbag cover 66 toward the rear upper side of the vehicle, and the folded portion 66D hits the lower portion 10A of the instrument panel 10 by elastic force. .

  When the steering column 13 is tilted, a large load that prevents the tilting operation is generated by sliding between the lower portion 10A of the instrument panel 10 and the folded portions 66C and 66D of the airbag airbag cover 66. It is supposed not to. Further, the folded portions 66C and 66D eliminate the gap between the lower portion 10A of the instrument panel 10 and the airbag airbag cover 66, thereby improving the appearance quality.

  As shown in FIG. 3, knee panels (knee pressing brackets) 70 serving as knee protection airbag movement restraining means are integrally formed on both outer side portions of the knee airbag support bracket 54 B in the vehicle width direction of the knee airbag mounting bracket 54. Is formed. These knee panels 70 are made of a rectangular plate whose longitudinal direction is the longitudinal direction of the vehicle.

  As shown in FIG. 1, the front portion 70 </ b> A of the knee panel 70 is located above the module case 62. Further, the front-rear direction intermediate portion 70B of the knee panel 70 extends toward the lower portion 10A of the instrument panel 10, and the rear portion 70C of the knee panel 70 approaches the back surface (inner side surface) of the lower portion 10A of the instrument panel 10. At the position, the vehicle panel extends upward along the back surface of the lower portion 10 </ b> A of the instrument panel 10.

  Therefore, when the knee airbag device 58 is tilted together with the steering column 13, the knee panel 70 is also tilted, so that the relative position between the knee airbag device 58 and the knee panel 70 does not change. Further, the knee airbag 60 is deployed as shown by the solid line in FIG. 2, and then the knee 82A of the driver 82 hits the knee airbag 60 inflated and deployed as shown by the two-dot chain line in FIG. When the airbag 60 presses the lower portion 10A of the instrument panel 10 and deforms it forward of the vehicle, the knee panel 70 is on the back side of the instrument panel 10, that is, the knee of the driver 82 of the inflated and deployed knee airbag 60. The lower part 10A of the instrument panel 10 is supported from the side opposite to 82A.

  As a result, the knee panel 60 can be restrained by the knee panel 70 from moving (escape) together with the lower portion 10A of the instrument panel 10 in the direction opposite to the knee 82A of the driver 82 (in the direction of arrow E in FIG. 2). It has become. Therefore, the knee airbag 60 can surely restrain the knee 82A of the driver 82.

  As shown in FIG. 1, the outer peripheral portion of the steering column 13 is composed of a column cover 76. A rear end portion 40B of the steering shaft 40 to which the steering wheel 44 is attached protrudes from the rear wall portion 76A of the column cover 76, and the adjustment lever 30 is attached from the side wall portion 76B of the column cover 76. The end of the fixed shaft 28 to be protruded.

  FIG. 4 is an enlarged cross-sectional view taken along line 4-4 of FIG. In FIG. 4, illustration of the inside of the cross section of the steering column 13 is omitted.

  As shown in FIG. 4, a column opening 80 is formed at a position separated by a predetermined distance above the airbag opening 68 in the lower portion 10 </ b> A of the instrument panel 10. The column opening 80 has a rectangular shape, and a column cover 76 is inserted in an upward direction of the vehicle (in the direction of arrow A in FIG. 4) and downward of the vehicle (in the direction of arrow B in FIG. 4) so as to be able to perform a tilt operation.

  As shown by a two-dot chain line in FIG. 4, the knee airbag 60 inflated and deployed from the airbag opening 68 into the vehicle interior is inflated and deployed at the vehicle width direction center portion 60 </ b> A on the vehicle lower side of the column cover 76. At the same time, both end portions 60B in the vehicle width direction are inflated and deployed to positions on the vehicle interior side of the knee panel 70 along the lower portion 10A of the instrument panel 10.

  Next, the operation of the present embodiment will be described.

  When the vehicle collides frontward (at the time of a frontal collision), the driver 82 seated in the driver's seat moves inertially toward the front side of the vehicle. For this reason, the driver's 82 knee 82 </ b> A is relatively close to the lower part 10 </ b> A of the instrument panel 10, and the gap between the knee 82 </ b> A and the instrument panel 10 is narrowed.

  On the other hand, at the time of a frontal collision of the vehicle, the collision is detected by an airbag sensor (not shown), and the inflator 64 of the knee airbag device 58 is activated by the airbag control device to inject high pressure gas into the folded knee airbag 60. Is done.

  As a result, as shown by a solid line in FIG. 2, the knee airbag 60 pushes open the airbag airbag cover 66 and expands and deploys between the knee 82 </ b> A of the driver 82 and the instrument panel 10.

  At this time, in this embodiment, the knee airbag device 58 and the knee panel 70 are integrally provided on the support cylinder 16 of the steering column 13. As a result, when the knee airbag device 58 is tilted together with the steering column 13, the knee panel 70 is also tilted integrally, so that the relative position between the knee airbag device 58 and the knee panel 70 does not change.

  Accordingly, regardless of the tilt position of the steering column 13, as shown by a two-dot chain line in FIG. 2, the knee 82A of the driver 82 hits the inflated and deployed knee airbag 60, and driving is performed via the knee airbag 60. When the lower part 10A of the instrument panel 10 pressed by the knee 82A of the person 82 moves in the pressing direction (the direction of arrow E in FIG. 2), the knee panel 70 hits the back surface of the lower part 10A of the instrument panel 10, The movement of the knee airbag 60 and the lower part 10A of the instrument panel 10 in the direction of arrow E can be reliably suppressed.

  As a result, in the present embodiment, the driver restraining performance of the knee airbag device 58 can be ensured even when the steering wheel 44 is tilted. Further, the knee airbag 60 is not increased in size and the design is not complicated.

  For example, when the driver 82 is small in size and the steering wheel 44 is moved to the lower side of the vehicle, the inflated and deployed position of the knee airbag 60 moves to the lower side of the vehicle, and the position of the knee panel 70 is also located below the vehicle. Move to the side. As a result, the knee panel 60 can reliably suppress the movement (escape) of the knee airbag 60 in the direction of arrow E. Therefore, the knee airbag 60 can reliably restrain the knee 82A of the driver 82 having a small body shape at an optimal position. When the driver 82 has a large body shape and the steering wheel 44 is moved to the upper side of the vehicle, the inflated and deployed position of the knee airbag 60 moves to the upper side of the vehicle, and the position of the knee panel 70 is also set to the upper side of the vehicle. Move to the side. As a result, the knee panel 60 can reliably suppress the movement (escape) of the knee airbag 60 in the direction of arrow E. Therefore, the knee airbag 60 can reliably restrain the knee 82A of the driver 82 having a large body shape at an optimal position.

  Further, in the present embodiment, the upper portion 66A of the airbag airbag cover 66 of the knee airbag device 58 is overlapped with the passenger compartment side of the upper peripheral edge portion 10B of the airbag opening 68 in the instrument panel 10. A lower portion 66B of the airbag cover 66 overlaps the vehicle compartment side of the lower peripheral edge portion 10C of the airbag opening 68 in the instrument panel 10. Furthermore, the vertical width W2 of the airbag airbag cover 66 is always set to a width that covers the airbag opening 68 even when the knee airbag device 58 is tilted together with the steering column 13. For this reason, even if the steering wheel 44 is tilted in the vehicle vertical direction, the airbag opening 68 is not exposed. For this reason, the appearance quality of the lower part 10A of the instrument panel 10 can be improved.

  In the present embodiment, the cross-sectional shape of the lower portion 10 </ b> A of the instrument panel 10 viewed from the vehicle width direction is an arc shape substantially along the movement locus of the airbag airbag cover 66 that accompanies the tilting operation of the steering column 13. ing. As a result, as the steering column 13 is tilted, the airbag airbag cover 66 can smoothly move in the vehicle vertical direction along the lower part 10A of the instrument panel 10. For this reason, the tilt operation performance does not deteriorate.

  Furthermore, in the present embodiment, a folded portion 66C is formed from the upper edge of the upper portion 66A of the airbag airbag cover 66 toward the vehicle front lower side, and the folded portion 66C is elastically applied to the lower portion of the instrument panel 10. 10A. Similarly, a folded portion 66D is formed from the lower end edge of the lower portion 66B of the airbag airbag cover 66 toward the rear upper side of the vehicle, and the folded portion 66D hits the lower portion 10A of the instrument panel 10 by elastic force. . As a result, no gap is generated between the lower portion 10A of the instrument panel 10 and the airbag airbag cover 66 by the folded portions 66C and 66D. For this reason, the appearance quality of the lower part 10A of the instrument panel 10 can be improved.
