摘要： The invention relates to a land vehicle (10) comprising: a front end (16) with a compartment (18) ; and an airbag (20) able to be received in the compartment.
The airbag comprises: an inflatable frame (26); an envelope (28) integral with the inflatable frame; and an inflating device (30).
The inflatable frame comprises at least three tubular-shaped structural members (32, 34); wherein, in an expanded configuration, each structural member extends substantially rectilinearly between a first end (36), linked to the body, and a second, free end (38).
In the expanded configuration, the envelope forms a closed chamber (49) with a substantially polygonal front panel (48) extending substantially vertically, each summit of said front panel being formed by the second, free end (38) of one of the structural members.
