Description

technical field [0001] The present invention relates to a knee protection airbag which is folded and accommodated in front of the knees of an occupant seated on a vehicle seat, and which can protect the knees of an occupant by allowing inflation gas to flow in and inflate when a vehicle collides. Background technique [0002] Conventionally, there is a structure disclosed in JP-A-2002-337649 as an airbag for knee protection. A conventional airbag for knee protection includes a bag-shaped airbag main body into which an inflation gas flows and inflates, and a tether provided in the airbag main body. [0003] The airbag main body of the airbag has a passenger side wall portion and a vehicle body side wall portion at the end of inflation, and the lower end side at the end of inflation is an upstream portion of the inflowing inflation gas, and the upper end side is a downstream portion of the inflation gas. The tether connects the passenger side wall portion and the vehicle body...
