2. Failure to lift the crushed injured out of the cab in time, missing the rescue time
[0005] Then, in the 130,000-kilometer driving test and the real car crash test, it was found that the "multifunctional vehicle front safety seat" still has the following defects: First, the small bearings used in the seat are often damaged due to poor radial bearing pressure. The outer ring is broken, and the conventional needle roller bearing with large load-bearing capacity, because the diameter of the inner and outer rings is too large, the seat is too bulky and heavy, and cannot be installed in a car.
The second is that when the test vehicle has just traveled more than 30,000 kilometers, the track of the seat is full of dust, oil, and rust. The track with a height of 0.03 to 0.08 mm higher than the standard tolerance of the bearing cannot allow the bearing to move.
The third is that because the reinforcement column 6 cannot rotate, when the car is subjected to a large collision force, the adjustment plate 5 will block the reinforcement column 6, the seat track and the front axle will be deformed, and the locking nails that lock the seat cannot be opened.
The fourth is that when the seat is installed on the car, the track hinders the rear passengers

Embodiment 1

[0067] Normally, the large end of the lock bolt 27 extends from the round hole 17 on the movable frame B into the hole 20 on the fixed frame G, and then is sealed and locked by the metal block 23 integrated with the manual control hammer A` and the movable suction head 22. Up the seat. At this time, the front surface of the movable frame B is in contact with the buffer belt B`, and the lower surface is pressed on the energy-absorbing bearings H, H` on the energy-absorbing plate 5 of the fixed frame, and the bearings I, I` on the front axle D and the upper part of the track 4, 4'contact, the lock bolt 27 is in contact with the rear wall L of the hole 20. The rear part is: the rear axle inner bearings 11, 11` are supported by the lower part of the track 15, 15`, and the rear axle outer energy-absorbing bearings 3, 3` are pressed by the energy-absorbing nails 9, 9`. This ensures that the seat advances: the baffle A is blocked by the buffer belt B'. Backward: The rear wall with a hole...

Embodiment 2

[0075] The energy-absorbing bearings 57 and 58 on the outer side of the rear axle only have an energy-absorbing effect. The inner bearings 11, 11' that need to move backwards after an accident, so the outer diameter of the energy-absorbing bearings 57, 58 does not need to be larger than the inner bearing 11, 11` outer diameter, there must be a sealing plate 59 at the rear of the fixed frame. The rest is the same as in Example 1.

Embodiment 3

[0077] When a car accident occurs, the diagonal upward force at the rear of the movable frame is applied to the rear energy absorbing frames 60, 60 on both sides of the fixed frame through the energy absorbing plate 66 on the movable frame, the energy absorbing nails 62, 62 of the embodiment 3 Because the hardness of the movable frame B is much larger than that of the energy-absorbing plate 66, the energy-absorbing plate 66 is deformed, and similarly, it also absorbs part of the kinetic energy of the seat, so the rear axle outer energy-absorbing bearings 3, 3 are no longer needed. . Others are the same as Embodiment 2, but also protect the key components: front axle bearings I, I, rear axle bearings 11, 11', movable frame, track, front and rear axles. All have achieved the purpose of avoiding or reducing the squeezing of the driver and passenger and facilitating rescue of the injured.

Abstract

An antisqueezing chair of air is disclosed for high safety. This chair including its back is installed to a movable frame able to move backward. The movable frame has front and rear axles with bearings and chair control system, and is installed to the fixing frame fixed to car floor and having energy-absorbing plate and bearing and two parallel tracks on it. When accident occurs, under the control of the said control system, the chair and driver or passenger can move backward, so preventing the seater from being squeezed.

Description

Technical field [0001] The invention relates to a car seat, in particular to an anti-extrusion car safety seat that can make the front row occupants safe. Background technique [0002] At present, there are many ways to protect the front-seat occupants in the event of an accident in the driving process. Renault of France has made the bumper into a honeycomb type to absorb energy. The most common method is to install seat belts and airbags on the car. If the current automobile safety equipment is perfect, there should be very few or no casualties for the driver and passenger in the event of an accident. However, according to statistics from relevant departments, one person is killed in a car accident every three minutes in the world, and more than 120 people die in a car accident in our country every day! About half of them are drivers and passengers, which fully shows that the existing car safety equipment is still insufficient. After careful observation, the inventor’s father, L...
