Gasbag for a pedestrian protection system and a motor vehicle equipped therewith

摘要

A gasbag for a pedestrian protection system, when in the inflated state encompasses a first, oblong central section and end sections angled away from the ends of the first central section. At least one first and one second membrane with differing permeability values are distributed over the sections in such a way that an average permeability of the end sections is lower than an average permeability of the first central section.

1. A gasbag for a pedestrian protection system in a motor vehicle, comprising:
a first central section that, when inflated, is oblong and substantially extends a width of the motor vehicle; a second central section that, when inflated, substantially extends the width of the motor vehicle; end sections which, when inflated, angle away from ends of the second central section, wherein the first central section is more strongly cushioned than the second central section and the end sections a plurality of check valves, each of the plurality of check valves being arranged between the first central section and one of the end sections, each of the plurality of check valves comprising:
a mesh sheet arranged between the first central section and each of the end sections, andan impermeable membrane secured at two opposing ends of each of the mesh sheets.
