Embodiment Construction
[0019] exist figure 1 , 2 Among them, an ejection device includes a cylinder 4 and a base 6, and the cylinder 5 is connected to the base through a rivet 8. The connection mode between the base and the cylinder body can also be connected by injection molding, and metal materials can also be injected. The cylinder 4 is provided with an inner chamber 41 and a gas generating chamber 7 surrounding the inner chamber; a pre-compressed spring 5 is arranged in the inner chamber 41; a gas generator is arranged in the gas generating chamber 7 . The cylinder block 4 is provided with a groove 10 adapted to the inner side beam of the seat.
[0020] In order to separate the base during ejection, the rivets are plastic rivets.
[0021] The ejection device is further provided with a side impact sensor and an ignition controller, and the ignition controller is electrically connected to the side impact sensor; the ignition device of the gas generator installed in the ejection device is electr...

The invention discloses an ejection device which comprises a cylinder body and a base, wherein, the cylinder body is connected with the base through rivets. The cylinder body is equipped with an inner cavity and a gas generating cavity embracing the inner cavity, a pre-compressive spring is arranged in the inner cavity, and a gas generator is arranged inside the gas generating cavity. A groove matched with the inside edge beam of a seat is formed on the cylinder body. The rivets are made of plastics. In addition, a side-impact sensor and an ignition controller are arranged, and the ignition controller is electrically connected with the side-impact sensor; and the ignition device of the gas generator mounted inside the ejection device is electrically connected with the ignition controller. A seat provided with the ejection device comprises a seat pan framework of the seat, a seat back and a sliding rail mechanism arranged under the seat pan framework. The ejection device is arranged between the outside edge beam of the seat pan framework of the seat and the sliding rail, and a plurality spherical hinges are mounted between the inside edge beam of the seat pan framework of the seat and the sliding rail. Because only one ejecting and turning device is used, the function of pushing seats and passengers to incline towards the centre is realized. The invention has the advantages of simple structure and practicality.
Description
technical field [0001] The invention relates to a vehicle safety device, in particular to an ejection device for a passenger vehicle and a tiltable seat using the device to protect occupants. Background technique [0002] In a side collision of a car, the occupant is very close to the dangerous area, resulting in a very high accident casualty rate. At present, the current restraint systems for occupant protection include side impact airbags and curtain airbags, which can play a buffer role in the collision between the occupant and the vehicle body, so as to reduce the impact on the occupant's head, chest, abdomen, and hips. impact, but such protective measures have their limitations, they can only reduce the degree of injury suffered by the occupant, but cannot fundamentally eliminate the threat to the occupant, and it is difficult to control the deployment range of the airbag to just cover the vital parts of the occupant, and when When the deformation of the vehicle body i...
