Problems solved by technology

[0005] The seat belts in the prior art basically adopt a flexible and fixed method. Only when the vehicle shakes too much, the passenger suddenly moves and pulls the seat belt, and the seat belt is suddenly stressed can the seat belt be tightened to prevent the passenger from moving; if the seat belt There is no sudden force but slow force. At this time, the seat belt will not be fastened and cannot protect the safety of passengers; such a seat belt cannot protect the lives of passengers at any time.

Embodiment 1

[0034] Such as figure 1 As shown, the present embodiment includes a seat 2, and a pressing arm 6 is arranged on both sides of the seat 2. The pressing arm 6 is connected by a rotating shaft 4. The pressing arm 6 can rotate up and down around the rotating shaft 4. The pressing arm 6 is connected with a lock The locking device 5 can limit the rotation of the pressing arm 6; further, the rotating shaft 4 is arranged horizontally, the rotating shaft 4 is installed on the back of the chair through the bearing seat, and the pressing arm 6 is connected with the rotating shaft 4 and is located on both sides of the seat 2 ; The pressing arm 6 is an arc-shaped structure;

[0035] Further optimization, the first rotating shaft 3 is also installed on the seat 2, the first rotating shaft 3 passes through the bearing, the bearing is fixedly installed on the seat 2, the first rotating shaft 3 is connected with an annular pressing arm 1, and the annular pressing arm 1 It can rotate up and do...

Embodiment 2

[0038] This embodiment is further optimized on the basis of Embodiment 1; the locking device 5 is locked by means of air pressure, and the locking device 5 includes a pneumatic cylinder, a control valve, a controller and a switch 10, and the working end of the pneumatic cylinder is hinged On the pressing arm 6 and the annular pressing arm 1, the pneumatic cylinder is connected with the control valve, the control valve is connected with the controller, the controller is connected with the switch 10, and the switch 10 is installed on the side of the seat 2. The locking device 5 not only has the function of locking, but also has the function of driving. When the pneumatic cylinder is working, the pneumatic cylinder drives the pressing arm 6 and the annular pressing arm 1 to rotate. When it rotates to a suitable position, the pneumatic cylinder stops working. Lock and fix the pressing arm 6 and the annular pressing arm 1.

[0039] Further optimization, the seat 2 is provided with ...

Embodiment 3

[0042] This embodiment includes a seat 2, and the two sides of the seat 2 are provided with pressing arms 6, the pressing arms 6 are connected by the rotating shaft 4, the pressing arms 6 can rotate left and right around the rotating shaft 4, and the pressing arms 6 are connected with a locking device 5, The locking device 5 can limit the rotation of the pressing arm 6; the rotating shaft 4 is vertically arranged, and the rotating shaft 4 has two, and the rotating shaft 4 is vertically installed on the seat 2 through a bearing, and the pressing arm 6 cooperates with the rotating shaft 4, further , the pressing arm 6 is an L-shaped structure; further optimized, the seat 2 is also equipped with a first rotating shaft 3, the first rotating shaft 3 passes through a bearing, the bearing is fixedly installed on the seat 2, and the first rotating shaft 3 An annular pressing arm 1 is connected, and the annular pressing arm 1 can rotate up and down around the first rotating shaft 3. The...

Abstract

The invention discloses a vehicle seat safety device which comprises a seat. The vehicle seat safety device is characterized in that press arms are arranged on two sides of the seat and connected through a rotating shaft and can rotate upwards and downwards or leftwards and rightwards around the rotating shaft, and a locking device is connected on each press arm and can limit rotating of the corresponding press arm. A flexible fixing mode of existing vehicle safety belts is changed into rigid fixing; after drivers and passengers adjust the press arms to proper positions, the press arms are fixed and kept still and stably fix the passengers in seats, and life safety of the drivers and the passengers can be protected even if accidents occur.

Description

technical field [0001] The invention relates to a safety protection device, in particular to a vehicle seat safety device. Background technique [0002] Seat belts are installed on automobiles, airplanes and other means of transportation to protect the safety of drivers and passengers; the main raw materials are polyester, polypropylene, nylon; seat belts are not just webbing, in addition to webbing, seat belts are assembled with other parts The ideal seat belt function process is: first, tighten it in time, and "press" the person on the seat without hesitation at the first moment of the accident. Then, relax moderately, and when the peak of the impact force has passed, or when the person has been protected by the airbag, the seat belt is properly loosened. [0003] Automobiles, airplanes and trains, as means of transportation, provide convenience for people's travel and improve the efficiency of people's life and work. However, the safety of automobiles, airplanes and trai...
