Embodiment 1

[0019] Such as Figure 4 As shown, the safety seat of this embodiment includes a seat body 8 and an ejection device 20 installed at the front lower part of the seat body 8. There are two ejection devices 20, which are installed on both sides of the seat body 8 respectively, and are connected with the sliding The rail 9 is fixed, and the slide rail 9 is slidably installed on the guide rail 10.

[0020] Such as figure 1 , 2 As shown, the ejection device 20 includes a base 1 fixed below the seat body 8 and a cylinder fixed on the base 1 by plastic rivets 7, the cylinder is provided with a gas generating chamber 2 and an inner chamber 4, the The opening of the gas generating chamber 2 is closed by the base 1. A gas generator 3 is installed in the gas generating chamber 2. The trigger device of the gas generator 3 is connected to a trigger control unit, and the trigger control unit includes a trigger control unit. device and a collision sensor electrically connected to the trigg...

Abstract

The invention aims to provide a safe seat capable of tipping backwards when the front part of a vehicle is impacted so as to reduce the possibility of injuring passengers in the impact process of the front part. The safe seat comprises a seat main body and an ejection device arranged under the front part of the seat main body, and is characterized in that the ejection device comprises a base fixed under the seat main body and a cylinder fixed on the base through a rivet; the cylinder is provided with a gas generation cavity; an opening of the gas generation cavity is sealed by the base; a gas generator is arranged in the gas generation cavity; a trigger device of the gas generator is connected with a trigger control unit; and the trigger control unit comprises a trigger controller and an impact sensor which is in electrical connection with the trigger controller. The safe seat ensures that the seat main body can be separated from a slide rail in time and tips backwards when impact happens through the ejection device arranged under the front part of the seat main body, which prevents passengers from impacting to a vehicle body due to tipping forwards and protects the personnel safety of the passengers better.

Description

technical field [0001] The invention relates to a safety device for a passenger vehicle, in particular to a safety device for a passenger seat. Background technique [0002] When a car collides with the front, the occupant continues to maintain a forward movement posture due to inertia, which will cause the key parts such as the head and chest to come into contact with the hard parts of the body, causing the occupant to be injured. At present, the commonly used protection method is to use the contact between the airbag and the occupant to buffer the collision energy. However, due to the uncertainty of the collision situation, the deployment of the airbag cannot completely protect the key parts. In addition, if the opening time of the airbag is not appropriate, it will cause rebound to the occupant. harm. [0003] A sliding ejection seat structure is proposed in the patent "ejection seat" (patent number: CN200610040137.5), which is as follows: a sliding device is installed b...
