Problems solved by technology

[0006] In the aforementioned Japanese Unexamined Patent Publication No. 10-217818, since an airbag or an inflator is arranged on the seat pan, unevenness is generated on the upper surface of the seat pan, and the occupant sitting on the seat may feel the unevenness through the seat cushion, resulting in Poor ride comfort
[0007] In addition, when installing or maintaining these airbags or inflators, etc., it is necessary to remove the seat cushion from the upper side of the seat pan, so the operability is poor.

Abstract

Provided is an occupant protection device capable of preventing deterioration of seating comfort of a seat and capable of being installed, maintained, and the like with good operability. A seat cushion is supported from below by a support member composed of a seat pan (4) and a spring (6), and an occupant protection device (10) is arranged on the lower side of the front portion of the support member. When a frontal collision of the vehicle is detected, the inflator performs a gas ejection operation, and the airbag (12) is inflated by the gas from the inflator. The inflated air bag (12) pushes up the front part of the support member upwards. As a result, the front portion of the seat cushion is pushed up by the seat pan (4) and the spring (6) or pushed up from the lower side to increase the density, thereby preventing or restraining the occupant's waist from moving forward.

Description

technical field [0001] The present invention relates to an occupant protection device for protecting an occupant on a seat of a vehicle such as an automobile during a collision, and particularly relates to an occupant protection device for restraining an occupant's waist to prevent the occupant's body from moving forward and downward during a frontal collision. Background technique [0002] As a system for protecting the occupants of a car in the event of a collision, in order to prevent the forward diving phenomenon in which the occupants slip under the lap belt in the event of a frontal collision even if the seat belt is worn, it is described in JP-A-10-217818 An occupant protection device in which an inflatable air bag is disposed between a seat cushion and a seat pan, and the front portion of the seat cushion is pushed up by inflating the air bag during a vehicle collision. [0003] Figure 12 It is a vertical cross-sectional view in the seat front-rear direction of the ...
