    摘要： A pedestrian airbag arrangement for a motor vehicle having a windscreen (23) is disclosed. The arrangement comprises an airbag (1) having an inflatable volume for the receipt of inflating gas and which is configured for deployment upon inflation so as to extend over or across at least part of the windscreen (23). The airbag (1) comprises a front layer of flexible material (2) and a rear layer of flexible material (3) and is characterised by a pair of internal tethers (9, 10) provided inside the inflatable volume, each said tether (9, 10) interconnecting said front and rear layers (2, 3) between a respective rear anchorage (11, 12) on said rear layer (3) and a respective front anchorage (13, 14) on said front layer (2), wherein said front anchorages (13, 14) are spaced from one another by more than any spacing between said rear anchorages (11, 12). The tethers (9, 10) are thus configured to become tensioned in a divergent manner between said front and rear layers (2, 3) upon deployment of the airbag (1) and thereby serve to control inflation of the airbag (1) such that the airbag adopts an inflated condition defining a cavity (26) between the airbag (1) and the windscreen (23).

    摘要： A pedestrian airbag for a motor vehicle is disclosed, the airbag defining an inflatable volume for the receipt of inflating gas. The inflatable volume is defined by a front layer (13) of flexible material, a rear layer (14) of flexible material and two end sheets (20) of flexible material; the front and rear layers (13, 14) being interconnected (17, 18) along their peripheral edges (15, 16) in a central region of the airbag, and the two end sheets (20) each being connected between respective peripheral edges of the front and rear layers (13, 14) at opposite end regions of the airbag.
