[0024] Example

[0025] In the existing technology, existing vehicles may cause traffic accidents due to the driver's own reasons and different road conditions during use. After an accident, it is necessary to rescue the person on the seat surface. At this time, if the person is unconscious, because he is sitting on the seat, his lower limbs will form multiple bends with his torso, which will make it difficult for outsiders to drag him out for rescue.

[0026] Please see Figure 1-5This utility model provides a technical solution: an easily adjustable vehicle seat, including a guide rail 1 for use in automobile seats, a seat cushion 2 slidably connected to the surface of the guide rail 1, a backrest 3 hinged to the end of the seat cushion 2, a grab handle 4 provided on the side of the seat cushion 2, the grab handle 4 can realize the angle adjustment of the backrest 3, a seat belt buckle 5 provided on the other side of the seat cushion 2, a base plate 6 fixed to the bottom of the seat cushion 2, the base plate 6 having several components, a telescopic component 7 provided on the surface of the base plate 6, in order to facilitate support for the lower limbs of trapped persons, thereby reducing the bending of the body surface and facilitating dragging and rescue, a support mechanism 8 provided on the surface of the telescopic component 7, the support mechanism 8 including... The telescopic assembly 7 includes a sliding plate 801 and a support plate 802. The sliding plate 801 is disposed on the surface of the telescopic assembly 7, and the support plate 802 is fixed to the bottom side of the sliding plate 801. The surface of the telescopic assembly 7 is provided with a drive structure 9, and the surface of the drive structure 9 is provided with a gripping component 10. In order to allow the support mechanism 8 to be stored when not in use and not to affect personnel activities, a telescopic assembly 7 is provided. The telescopic assembly 7 includes a lead screw 701 and a first bevel gear 702. The lead screw 701 is bearing connected between two base plates 6, and the first bevel gear 702 is fixed to the end of the lead screw 701. The sliding plate 801 is threaded onto the surface of the lead screw 701.

[0027] To ensure uniform force distribution on the surface of the support plate 802 and prevent damage due to uneven force, two sets of telescopic components 7 are provided. These two sets of telescopic components 7 are symmetrically distributed about the longitudinal central axis of the slide plate 801. To allow the trapped person's lower limbs to be lifted more quickly onto the surface of the support plate 802, the support plate 802 and the slide plate 801 form an "L" shape. The end face of the support plate 802 near the person is arc-shaped. To ensure synchronous operation of the two sets of telescopic components 7, a drive structure 9 is provided. The drive structure 9 includes a second bevel gear 901 and a connecting shaft 902. The second bevel gear 901 meshes with the side of the first bevel gear 702. The connecting shaft 902 passes through the center of the second bevel gear 901. The second bevel gear 901 is larger than the first bevel gear 702. This design creates a gap between the connecting shaft 902 and the lead screw 701. The speed difference improves the efficiency of the rotating lead screw 701. The mounting point of the connecting shaft 902 is close to the front end of the seat cushion 2. This design reduces the impact of the vehicle's B-pillar obstructing the rotation operation. In order to install the drive structure 9 onto the surface of the seat cushion 2, the central section of the connecting shaft 902 is rotatably sleeved with a fixing block. The fixing block is fixedly connected to the bottom of the seat cushion 2. In order to improve the speed of the rotating parts by the rescuers and thus improve the rescue efficiency, a gripping component 10 is provided. The gripping component 10 includes a side plate 1001, a groove 1002, a rotating shaft 1003, and a gripping plate 1004. The end of the connecting shaft 902 extends through the side of the seat cushion 2. The side plate 1001 is fixed to the end of the connecting shaft 902. The groove 1002 is opened at the end of the side plate 1001. The rotating shaft 1003 is rotatably connected to the inside of the groove 1002. The gripping plate 1004 is nested and fixed to the surface of the rotating shaft 1003.

[0028] The seat body is composed of guide rail 1, seat cushion 2, backrest 3, grab handle 4, and seat belt buckle 5. The model of the seat body is A-22, and its supplier is Beijing Zhunixing Information Technology Co., Ltd.

[0029] In terms of working principle or structural principle, during daily use, passengers can use the grab handle 4 to adjust the angle of the backrest 3, and can also slide the seat cushion 2 on the guide rail 1 to adjust the position and increase riding comfort.

[0030] If a vehicle accident occurs and an unconscious passenger needs to be rescued, bending of the passenger's lower limbs and hips can hinder the towing rescue. Rescuers can manipulate the grab plate 1004 to rotate it within the groove 1002, creating an angle between the grab plate 1004 and the side plate 1001. Rescuers can then use the grab plate 1004 to rotate the side plate 1001 and the connecting shaft 902. Because the connecting shaft 902 is connected to the lead screw 701 via a first bevel gear 702 and a second bevel gear 901, rotating the connecting shaft 902 will cause the lead screw 701 to rotate. During the rotation of the lead screw 701, the threads on its surface will displace the sliding plate 801 and the support plate 802, thereby lifting the trapped passenger's lower limbs so that they are at the same height as the hips, facilitating the towing rescue.

[0031] In summary, this device has advantages such as adjustability and ease of rescue.
