bracket 21 is also provided with amanifold 22 for distributing gas, and a gas injection port of theinflator 20 is connected to a gas inlet of themanifold 22. Themanifold 22 is provided with two gas outlets and theduct 12 is connected to one of the gas outlets. - A
webbing 31 of the seatbelt apparatus is led along a front surface of theback frame 3. Thewebbing 31 is formed of a non-inflating normal belt material. One end side of thewebbing 31 is mounted to theside frame 1 a with ananchor 32. A midsection of thewebbing 31 passes through atongue 33. The other end side of thewebbing 31 passes through theshoulder anchor 6 provided on an upper portion of a side surface of a cabin (pillar section or the like), and is connected to the seatbelt retractor 7 so as to be capable of being retracted. - A buckle device 34 to which the
tongue 33 is detachably connected is provided on an outer surface of theside frame 1 b. Thewebbing 31 includes a portion on thelap anchor 32 from thetongue 33 which corresponds to alap portion 31 a to be led along a front surface of a lumbar part or an abdominal part of the passenger seated on the seat, and a portion on the side of theshoulder anchor 6 which corresponds to ashoulder portion 31 b to be led along the front surface of the upper half body of the passenger in a state in which thetongue 33 is connected to the buckle device 34. - An
inflatable lap bag 35 is provided along thelap portion 31 a. - The
lap bag 35 includes, although not shown, an inflatable bag body arranged along thelap portion 31 a and a cylindrical cover that covers the bag body and thelap portion 31 a. The bag body is in a state of being folded into a long and flat shape along thelap portion 31 a in a normal state. In this embodiment, the cover has a size which fits an outer periphery of the folded body of the bag body when the bag body is in a non-inflated state, and is configured to be expandable in the circumferential direction to accommodate inflation of the bag body when the bag body is inflated. - In this embodiment, the cover is formed of a knitted fabric which is similar to the above-described mesh webbing of the above-described
seat bag 10, which is expandable in the circumferential direction but expands little in the longitudinal direction. Therefore, when the bag body is inflated, the mesh of the cover is expanded in the circumferential direction in association with an expansion of the cover in the circumferential direction, and consequently, the longitudinal dimension of the cover is reduced (shortened). Accordingly, thewebbing 31 is tensed and hence comes into tight contact with the passenger's body. - It is also possible to connect one end of the
lap bag 31 to a distal end of thewebbing 31 to secure the other end of thelap bag 35 to theside frame 1 a with the anchor. - A distal end of the
gas introduction duct 36 is connected to an end portion of thelap bag 35 on the side of theanchor 32. A proximal end of theduct 36 is connected to the other gas outlet of the manifold 22. - Subsequently, an operation of the passenger restraining apparatus will be described.
- When the inflator 20 is activated and injects gas in case of emergency, such as vehicle collision, gas from the inflator 20 is branched to the
respective ducts seat bag 10 and thelap bag 35, respectively. Accordingly, theseat bag 10 and thelap bag 35 are inflated. - Since the
seat bag 10 is inflated under the seat cushion and pushes the seat cushion upward, the front portion of the seat cushion is pushed upward, or is hardened, so that forward movement of the lumbar part of the passenger can be prevented. - Also, since the length of the
lap bag 35 is shortened in association with inflation thereof, theentire webbing 31 is tensed, and comes into tight contact with the passenger's body. Consequently, a portion of the passenger from the femoral region to the lumbar part is strongly restrained to the seat owing to the webbing tightening effect and the sandwiching effect achieved by the front portion of the seat cushion which is pushed upward or hardened by theseat bag 10. In this case, an impact applied to the lumbar part or the abdominal part of the passenger is absorbed by theinflated lap bag 35. - In this passenger restraining apparatus, the
inflator 20 is mounted to thespindle 2 as described above, and hence a vacant space around thespindle 2 can be used effectively. In this embodiment, since thesingle inflator 20 is adapted to inflate theseat bag 10 and thelap bag 35, only one inflator is used, and hence a simple configuration is achieved. - Referring to
FIG. 3 toFIG. 5 , an embodiment in which theinflator 20 is installed above a seat pan will be described. - A
first recess 41 for accommodating the inflator 20 and the manifold 22, and asecond recess 42 for accommodating theseat bag duct 12 are provided on aseat pan 40. Thefirst recess 41 extends laterally of theseat pan 40, and aninsertion hole 43 for inserting theduct 36 for thelap bag 35 is provided so as to face toward a side surface of theseat pan 40. - A
