摘要： The object is to provide a leg protection device for vehicle occupants which has an airbag of which thickness when inflated is small so that the airbag can be rapidly inflated even with a gas generator having small generating capacity and which can sufficiently receive and stop occupant's legs. As a vehicle equipped with a leg protection device (1) comes into a frontal collision, a gas generator (5) is actuated to spout out gas through gas ports (5b) so as to initiate the inflation of an airbag (90A). Gas from the gas generator (5) first flows into a first chamber (116) so that the first chamber (116) starts to inflate. Subsequently, the gas in the first chamber (116) flows through the inlets (22a) to inflate the second chamber (18). According to the initiation of inflation of the airbag (90A), an interior panel (2) is pressed by the airbag (90A) so as to be torn along tear lines (6), forming flaps (25). The airbag (90A) is deployed into a vehicle cabin to extend along the front surface of the interior panel (2). The inside of the airbag is divided into said first chamber and the second chamber by a partition panel (96) and the partition panel is provided with at least one vent hole (112) for allowing the communication of gas.

摘要： An airbag that is hardly influenced by heat from an inflator when a strap for restricting a shape of inflation of the airbag ruptures and an airbag system having this airbag are provided. A strap 20 is provided within the airbag 10 to restrict the shape of inflation of the airbag 10. The strap 20 is what connects right and left sides of the airbag 10. The strap 20 is made of a fabric woven by warps and woofs and is arranged so that a fine line direction of the fabric runs in a direction oblique to a longitudinal direction, i.e., a tensile direction, of the strap 20. When predetermined or more tensile force is applied to the strap 20, the texture of the fabric becomes loose and the strap ruptures such that the warps and woofs of the fabric composing the strap 20 are pulled out of the texture of the fabric ( Fig. 2 ).

摘要： In order to realize a prompt development of an airbag without losing shock-absorbing characteristics, even in the airbag that is partitioned into a plurality of chambers in the inner part thereof, an inner part of an airbag (10) is partitioned into a first chamber (1) at a center, and a second chamber (2) surrounding the first chamber (1), by a first and a second inner panels (22A, 22B). In a rear panel (14), a venthole (18) for allowing the second chamber (2) to communicate with an outer part of the airbag (10) is provided. A lid member (60) covers the venthole (18) and is combined with a vicinity of the venthole (18) of a rear panel (14) by a tear seam (63). The lid member (60) is connected to the second inner panel (22B) by a tether (70). At an initial stage of an expansion of the airbag (10), the venthole (18) is covered with the lid member (60). When the airbag (10) is expanded more than the predetermined amount, the lid member (60) is stretched by a second inner panel (22B) via the tether (70) and torn off from the venthole (18) resulting in opening the venthole (18).
