Embodiment Construction

[0014] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0015] As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the safety protection device of the present invention is composed of a protection arm (1), a base (2), a ratchet (4), a spring (7) and the like. Base (2) is fixed with the top of seat (11) by bolt hole (10), and axle (5) and base (2) are one. The protective arm (1) is integrated with the ratchet (4), and the non-return pawl (3) is fixed on the base (2), and cooperates with the ratchet (4) under the action of the compression spring (8); the nut (6) will protect the The arm (1) and spring (4) are fixed on the shaft (5). The function of the spring (7) is to make the protective arm (1) generate a certain frictional force when it rotates, so as to ensure that it can hover in the air naturally; The non-return ratchet (3) can be disengaged from the ratchet (4) when the handle (9) is turned, and t...

Abstract

Disclosed is a passenger safety guard device, comprising a guard arm(1), a base(2), a check pawl(3), a ratchet wheel(4), a shaft(5), a nut(6), a spring(7) and a pressure spring. The invention is characterized in that the base(2) is fixed to the upper part of a seat(11) through a bolt hole(10); the shaft(5) is integrated with the base(2) into a whole and the guard arm(1) is integrated with the ratchet wheel(4) into a whole; the check pawl(3) is fixed on the base(2); the nut(6) fixes the guard arm(1) and the spring(4) on the shaft. When in use, a passenger can turn the guard arm to a proper position above the shoulder and in the case of an emergency, the guard device can prevent the body of the passenger from moving upwards or forwards, safeguarding the safety of the passenger while not injuring the passenger itself; after use, the guard arm can be returned to the proper position by pulling an operation handle(9). The invention has the advantages of simple operation and good guard effect.

Description

technical field [0001] The invention relates to the field of traffic safety protection, in particular to a passenger safety protection device applicable to seats of vehicles, ships and airplanes. Background technique [0002] Seat belt is a necessary safety protection device on current vehicles (cars, boats, airplanes, etc.). Generally, the driver's seat belt is a shoulder sling type, and the passenger's seat belt is a abdominal horizontal pull type. Although the safety protection effect is relatively obvious, it also brings inconvenience to the user to varying degrees, especially the passenger seat belt. It will injure the internal organs of the passengers in the accident. Practice has proved that the effective protective device should still be aimed at the shoulders. [0003] There is an existing invention patent named "Vehicle Shoulder Anchor Bolt Installation Structure", and its patent number is 02145756.5, which discloses a vehicle shoulder safety device installation s...
