It means a backrest with better shock absorption. 5 [Previous technology] When a vehicle such as a wheelchair or a scooter is traveling on a bumpy road, the vehicle will not only have front-to-back vibration, but also vertical or left-to-right vibration. However, the shock absorption of the backrest is generally poor, resulting in riding People are unwell. What's more, when the vehicle is traveling, it does not travel at a constant speed. It must sometimes accelerate and decelerate from time to time. When it encounters an emergency, it must stop momentarily. However, when the vehicle suddenly changes speed, The user will also lean forward due to the relationship of inertia, and then immediately lie down on the backrest. At this time, the user will collide with the backrest of the vehicle seat due to such a sudden speed change. The reaction force will be transmitted to the user again. 15 When the impact force is greater, the reaction force is greater, which may cause the user to cause physical injury. [New content] The main purpose of this creation is to provide a backrest of the vehicle, which can effectively reduce the impact force of the user suddenly lying down on the backrest when the vehicle suddenly changes speed, and at the same time, slow down The release of the reaction, thereby effectively providing the user with a more stable and comfortable ride. In order to achieve the purpose of pre-disclosure, the back of this creative vehicle includes: a fixed piece with a front and a back; a movable piece made of hard material, and the next page (when the new instruction page is insufficient) , Please note and use the continuation page) -4- M256165-^ 一 ·-New instruction manual, the continuation page has a front and a back, and the moving film is set on one side of the fixed film at a predetermined distance, and the moving film The front surface is opposite to the front surface of the fixed piece; a plurality of buffer bodies are provided between the movable piece and the fixed piece; thereby, providing a user with a more stable and comfortable riding feeling. 5 [Embodiment]

The drawings used are briefly explained as follows: The first drawing is a schematic diagram of the first preferred embodiment of this creation applied to a wheelchair; The second diagram is a sectional view of the first diagram along the direction of 2-2; the third diagram is a schematic view of the force similar to the second diagram; the fourth diagram is a sectional view of the second preferred embodiment of the present invention applied to a car seat cushion; And 15 The fifth figure is a cross-sectional view of the third preferred embodiment of the present invention. Please refer to the first and second figures. The backrest (1) of the vehicle provided in the first preferred embodiment of the present invention can be a scooter or a wheelchair. This project uses the wheelchair (10) as an example. The wheelchair (10) has a cushion (11), and the back 20 (1) of this creation is provided at the rear end of the seat cushion (11) in a manner of approximately vertical extension; the back (1) includes: a fixed Sheet (20), a movable sheet (30), a plurality of buffer bodies (40), and an outer layer (50), wherein: the fixing sheet (20) is a hard shell plate, and has a front surface (21) and a back surface (22) ). The fixing piece (20) is connected to the seat cushion (11) in a longitudinal direction, and the front -5- M256165 new manual 朝) faces the wheelchair (⑻ front, and the back (22) faces toward the rear of the wheelchair (ί)). This' sets the backrest (1) on the wheelchair (10). The famous movable film (30) is a hard shell plate, which has a front surface (31) and a back surface (32). Before the fixing piece (20), and its back face (32) is opposite to the front face (21) of the fixing piece (20), the back face (32) of the movable piece (30) and the cymbal fixing piece (2) On the front side (2ι), there is a accommodating space (33). Buffers (40) such as 〇 钂 are compression springs in this embodiment. The buffers (40) are arranged at a distance of Hx at a predetermined distance. In the accommodating space (33), 10 and the axial direction of each of the buffer bodies (40) is perpendicular to the front surface (21) of the fixed piece (20), and one end of each of the buffer bodies (40) is connected to the movable piece The back side (32) of (30), the other end of which is connected to the front side (21) of the fixed piece (20). The outer layer (50) is the fixed piece (20), the movable piece (30), and Buffers (4 0) Cover it; In addition, a foam layer (not shown) can be filled between the outer layer (50) and the movable film (30) 15. The above is the first preferred embodiment of the creation Structure, in conjunction with the third figure, in normal driving conditions, the user can support the back by lying on the backrest (1), and the user can control the wheelchair (10) to move forward with ease. At the same time, the foam layer of the backrest (1) can provide a soft touch of 20, so that the user will not feel that the back is hard and difficult to rest. In addition, when the driving speed of the wheelchair (10) changes suddenly, the user's body Lean forward under the influence of inertia, and then lie down on the backrest G). At this time, the movable plate (30) will be forced to compress the buffers (4) by force ^. At this time, the Waiting for the buffer body (40) can absorb part of the impact force, and can slow down the reaction -6- M256165 ----- New manual, the release of the force of the continuation page, so that it can be transmitted to the use The reaction force on the person is minimized, and the outer layer (50) can prevent the user's finger from being accidentally inserted When the fixing plate (20) and between the movable plate (30), was accidentally squeezed. 5 Furthermore, when the wheelchair (10) travels on a bumpy road, it will not only have front-back vibration, but also left-right or vertical vibration. The compression deformation and shear deformation of these buffers (40) can be used. Provide cushioning in all directions, so that passengers have excellent riding comfort. Of course, the main function of the "backrest of the vehicle" in this creation can not only absorb vibrations in different directions, but also absorb the impact force generated by the user lying down on the backrest, and slow down the release of the reaction force. Therefore, it can be applied The backrest structure of various vehicles is not limited to wheelchairs. Similarly, as long as the cushioning body of the backrest can provide an appropriate cushioning force, it is in line with the main purpose of this creation. For example, please refer to the fourth figure, It is the backrest (60) of the second preferred embodiment 15 of this creation, which is applied to a car seat cushion (not shown). The difference from the above disclosed embodiment is that the buffer system of this embodiment is hydraulic One end of each of the hydraulic rods (61) is provided on the movable piece (62), and the other end is provided on the fixed piece (63), whereby when the vehicle changes speed, the hydraulic pressure The rod (61) will bear the pressure and compress, offsetting 20% of the impact force; at the same time, the hydraulic rod releases energy slowly, making the reaction force release more pronounced, so that the user I ca n’t even feel the reaction This makes the backrest (60) better shock-absorbing effect, the same, of course, these buffers can also use air pressure rods to achieve the same effect; In addition, refer to the fifth figure, this is the third in this creation In the preferred embodiment, the backrest M256165 new instruction sheet $ 70 (70), the cushioning system uses latex balls (71) with good elasticity (you can also use Uli rubber blocks ... etc.).
