Description
Technical Field
The present invention relates to a passenger protection device for a seat in an automobile, and more particularly, to a lifting device for preventing a passenger from sinking, which restrains the hip of the passenger to prevent the body of the passenger from moving forward and downward in a frontal collision.
Background
The automobile safety belt is the most cheap and effective safety device, and can restrain the passenger when in collision, avoid the passenger to have secondary collision with the steering wheel and the instrument board when in collision or avoid the passenger to rush out of the automobile when in collision, as shown in fig. 1, when the automobile does not have collision, the safety belt 5 can restrain the passenger 4 on the seat 3, and the lower part of the safety belt 5 restrains the hip of the passenger 4, and the upper surface 1 of the seat cushion forms an included angle α with the horizontal plane 2.
The "submarine phenomenon" in a collision accident is a phenomenon in which, in a front collision of a vehicle, a seat belt is worn by a passenger seated in a vehicle seat, and the seat belt is worn by the hip of the passenger along a seat surface due to inertia of the vehicle collision.
When a frontal collision occurs in a vehicle, the restraint of the seat belt on the passenger is applied to the hip of the passenger due to the presence of the seat belt in a state where the "dive phenomenon" does not occur, and the damage of the seat belt on the hip of the passenger is not caused, but when the "dive phenomenon" occurs, the restraint of the seat belt 5 on the passenger 4 restrained on the seat 3 is applied to the abdomen of the passenger, which is a part with more soft tissues of the human body, due to the seat belt being drilled out of the hip of the passenger and the hip moving forward and downward along the seat surface, as shown in fig. 2. Conventional devices for preventing the occurrence of the passenger's ' dive phenomenon ' are airbag structures, and the disposable nature of the airbag structures causes the subsequent maintenance cost of the vehicle to be increased.

the generator is arranged in the middle of the vertical plate of the base and is connected with the inlet of the air cylinder;
the piston rods are arranged in the air cylinder, and the two piston rods respectively extend towards the left side and the right side of the base;
the connecting rod rotating shafts are transversely arranged in corresponding side strip-shaped holes in the front vertical plate and the rear vertical plate and are connected with corresponding piston rods;
the U-shaped clamp spring is connected with the connecting rod rotating shaft on the corresponding side and clamped on the bottom plate;
the stay bar is hinged between the corresponding side connecting rod rotating shaft and the lifting beam.
Furthermore, a clamping groove is formed in the bottom surface of the base corresponding to the U-shaped clamping spring, and the U-shaped clamping spring is clamped in the clamping groove.
Furthermore, a pin hole is axially formed in the rotating rod rotating shaft along the piston rod, and the piston rod penetrates through the corresponding pin hole and then is connected with the rotating rod rotating shaft through a nut.
Furthermore, the left and right side stay bars are respectively two and are symmetrical front and back.
Further, the cylinder inlet is connected with the generator through threads, and fastening sealant is coated on the threads to increase the air tightness of the connection.
The invention has the beneficial effects that:
when the vehicle has a frontal collision, the lifting mechanism jacks up the foaming layer of the seat cushion to drive the upper legs of the passenger to rotate around the rotation center of the hip part to move upwards, and the included angle between the upper surface of the seat cushion and the horizontal plane is increased, so that the trend of the upward and downward movement of the hip part of the passenger is inhibited, and the risk of soft tissue injury to the belly part of the passenger in the collision process is reduced. After the lifting mechanism is used, the generator and the U-shaped clamp spring only need to be replaced, so that the lifting mechanism can be recycled, is convenient to replace, and can effectively reduce the maintenance cost of the vehicle.
