Airbag for deputy driver's seat

Abstract

The present invention provides a gasbag for a sub driving seat. In the gasbag of the present invention for sub driving seat, concave portion is installed along top and bottom direction approximately at passenger protecting part of the gas main body. Top part at inside of the passenger protecting part at the protruding end composing the concave part connect with part nearby gas input by a lacing, when the gasbag main body expansion is completed. The lacing divided into a front part and a rear part, the rear part makes the back part which is wider than the front part connecting with inside top part in entire area. The front part forms eudipleural shape with the center of the gas input, and the front part connecting with part of gas input at least right and left sides at periphery part of gas input, thereby the front part can equably tow the rear part approximately in top and bottom entire area.

Description

technical field [0001] The present invention relates to an airbag for a passenger seat, which is folded and accommodated on the upper surface side of the instrument panel in front of the passenger seat of the vehicle, protrudes upward when inflation gas flows in, and simultaneously blocks the instrument panel. The way between the upper surface and the windshield above the dashboard expands towards the rear side of the vehicle. Background technique [0002] Currently, as an airbag for a passenger seat, as shown in JP-A-2006-176091, it has a structure in which an airbag facing the front side is provided near the center in the left-right direction of the occupant protection part disposed on the rear side when inflation is completed. Inside the airbag main body with the structure of the recessed recess, a tether is provided, which connects the vicinity of the recess and the peripheral part of the gas inflow port arranged on the lower surface of the front end side when the inflat...

AI Technical Summary

Problems solved by technology

[0004] However, in the existing airbag for the passenger seat, as a tether, only a plurality of rope-like materials are arranged side by side in the front and back, and are respectively combined with the main body side of the airbag to form a structure. When the part protrudes toward the passenger side, when the tether stretches toward the passenger side as the occupant protection part protrudes, the portion near the gas inflow port is also stretched toward the passenger side due to the tether, and the recessed portion is formed toward the airbag. The inner top part of the passenger protection part on the protruding end side of the main body inner peripheral side may protrude greatly toward the passenger side, and there is room for improvement in suppressing the protruding toward the passenger side.
