- the pair of side hinge regions 170a and 170b are formed as regions without a tear line 156 in each of the side portions 168a and 168b of the front region 150.
- the pair of side hinge regions 170a and 170b are formed so that the axes of the hinges 160a and 160b (see FIG. 4B) are parallel to each other when viewed facing the front region 150. With this configuration, the cover doors 154a and 154b can be wide open in the direction of 180 ° to each other to form a wide opening.
- FIG. 5 is a sectional view taken along line BB of the steering wheel 106 of FIG. 3 (a).
- FIG. 5A illustrates the state of the cover member 110 before cleavage.
- the front area 150 of the cover member 110 covers the occupant side of the airbag module 105.
- the upper surface region 158 extends from the upper end of the front surface region 150 to the front of the vehicle and covers the upper surface of the airbag module 105.
- FIG. 5B illustrates the state of the cover member 110 after cleavage.
- the upper surface region 158 of the cover member 110 in consideration of safety during expansion and deployment of the cushion 104 (see FIG. 6A and the like), is widely opened. There is. More specifically, in the upper surface region 158, the inflator 112 of the airbag module 105 is installed and fixed to a position about a distance S1 away from the module installation surface 109 on the front side of the vehicle as compared with the module installation surface 109. It is configured to open across.
- the cover doors 154a and 154b are located on the front side of the upper surface area 158 from the front area 150 side to the front side of the vehicle from the module installation surface 109 (see FIG. 6B). It is formed to include a range extending to. That is, the tear line 156 extends from the vicinity of the center of the front area 150 to the front side of the vehicle with respect to the module installation surface 109 near the center of the upper surface area 158.
- FIG. 6 is a diagram illustrating the cushion 104 at the time of expansion and deployment and the occupant 138 in a non-regular seat (commonly known as out-of-position) according to FIG. 5 (b).
- FIG. 6 illustrates the cushion 104 and the occupant 138 when viewed from the left side in the vehicle width direction.
- the angle of the steering 106 can be changed as appropriate, and in a normal vehicle, the upper part of the steering 106 is tilted forward as compared with FIG. 5A.
- the cushion 104 may approach the head 140 of the occupant 138 from below, for example, when leaning out from the seat 102 (see FIG. 5).
- the cover doors 154a and 154b are opened to the left and right, so that the cover doors 154a and 154b are suppressed from being pushed upward by the cushion 104. There is. Therefore, even if the head 140 of the occupant 138 is located above the cover member 110, the push-up of the head 140 of the occupant 138 due to the cover doors 154a and 154b is prevented.
- the cover member 110 opens not only the front area 150 but also the upper surface area 158.
- the upper surface region 158 opens wider to the front of the vehicle than the module installation surface 109. Therefore, when the head 140 of the occupant 138 is located above the cover member 110, the cushion 104 can expand in front of the vehicle of the head 140 so as to avoid the head 140 of the occupant 138. At this time, since the expansion pressure toward the upper side of the cushion 104 is also dispersed in the front of the vehicle, the push-up of the head 140 of the occupant 138 by the cushion 104 is suppressed.
- FIG. 7 is a diagram illustrating an occupant 138 in a state close to the steering wheel 106 in FIG. 5 (a).

- FIG. 7B is a view of the cover member 110 of FIG. 7A and the head 140 of the occupant 138 as viewed from above.
- the airbag device 100 as a guideline for the size of the opening of the upper surface region 158, for example, the upper surface region 158 is moved from the chin tip 141 of the occupant 138 in a state where it comes into contact with the steering 106 and has stopped moving forward to the vehicle front side. It is preferable to open over a range of 35 mm or more (S2> 35 mm).
- FMVSS208 Federal Motor Vehicle Safety Standards
- OOP non-regular seating
- restraint devices such as airbags and seat belts for occupants.
- OOP test the load received by the human dummy is measured when the human dummy is in close proximity to the airbag.
- the steering wheel 106 of the present embodiment When the steering wheel 106 of the present embodiment (see FIG. 7A) is applied to the above OOP test, the upper part of the steering wheel 106 is tilted forward at an angle of about 18 ° to 27 ° like a general steering wheel. However, there is no rim 114 on the upper side. Therefore, in the human body dummy imitating the occupant 138, the head 140 moves forward without touching the structure, and the chin tip 141 and the chest 142 are in a state of being close to the cover member 110. In a state where the forward movement of the occupant has bottomed out, as illustrated in FIG.
- the upper surface region 158 of the cover member 110 opens from the chin tip 141 of the occupant 138 to the front side of the vehicle over a range of 35 mm or more.

- Hybrid III hybrid three
- Thor dummy Hybrid III dummies are available in multiple models that imitate people of different physiques and genders.
- the Thor dummy was developed as a successor to the Hybrid III dummy and is modeled only on men of average physique.
- the AF05 model of the Hybrid III dummy imitates a woman with a small physique.
- the seat 102 (see FIG. 1A) is often positioned in front of the adult man and the like, and the vehicle is often driven in a posture closer to the steering wheel 106. Therefore, the head of a small adult female is more likely to be located above the cover member 110 of the steering 106 than that of an adult male or the like.
- smaller adult women have lower physical tolerance and are more likely to have higher injuries than adult men.
- the upper surface region 158 of the cover member 110 is 35 mm or more from the chin tip 141 of the AF05 model to the front side of the vehicle. It may be opened over. This makes it possible to adequately ensure the safety of small adult women.
