Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to automotive seats and vehicles having them. Background Technology

[0002] With the continuous development of smart cockpit technology, existing technology has led to the development of car seats with zero-gravity functionality. Inspired by astronauts' seats in space, this innovative ergonomic design allows passengers to experience less pressure than their own weight, creating a feeling of weightlessness and floating. Zero-gravity seats ensure passenger comfort, providing more supportive fit, reducing localized pressure points, alleviating fatigue during long journeys, and helping to reduce health problems caused by improper posture.

[0003] Furthermore, car seats with zero-gravity functionality are typically equipped with the ABTS (All Belt Tether to Seat) system, ensuring all seatbelt anchor points are mounted on the seat to comply with regulations during adjustments. However, in zero-gravity conditions, with a passenger lying on a reclined backrest at an angle exceeding 45°, the powerful inertia of a collision can cause the body to move forward and downward. In this situation, the seatbelt may exert lateral strangulation on the neck, compromising safety and potentially causing injury.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] To address or improve to some extent the poor safety of existing car seats with zero-gravity functionality, this invention provides a car seat. The car seat includes: a backrest frame having a zero-gravity position; a support bracket movably disposed on the upper part of the backrest frame, having a first position away from the backrest frame and a second position close to the backrest frame; and a seatbelt configured to press against the support bracket, and when the backrest frame is in the zero-gravity position, the seatbelt is configured to drive the support bracket from the first position to the second position under the action of an external force.

[0006] The skilled in the art can understand that the utility model discloses a car seat including a backrest framework, a support bracket and a safety belt. The backrest framework has a zero-gravity position, which can provide more conformal support for the passenger, reduce local pressure points, reduce the fatigue of long-time riding, and ensure the comfort of the passenger. The support bracket is movably arranged at the upper part of the backrest framework and has a first position away from the backrest framework and a second position close to the backrest framework. The safety belt can be pressed on the support bracket to apply appropriate external force to the support bracket. When the backrest framework is in the zero-gravity position, the safety belt is configured to drive the support bracket to move from the first position to the second position under the action of appropriate external force (for example, when the vehicle collides). In this way, the safety belt will move downward with the passenger to a certain extent, ensuring that the safety belt always acts on the shoulder of the passenger and preventing lateral strangulation, thereby improving the safety of the car seat.

[0007] In the preferred technical scheme of the car seat, the support bracket includes a top wall located at the upper part of the backrest framework and capable of supporting the safety belt, and a side wall configured to extend downward from the circumferential edge of at least part of the top wall, and a fixing hole extending vertically and connecting the backrest framework is formed in the side wall to allow the support bracket to move from the first position to the second position. The top wall located at the upper part of the backrest framework can stably and reliably support the safety belt. In addition, the vertically extending fixing hole formed in the side wall can allow the entire support bracket to move downward from the first position to the second position relative to the backrest framework.

[0008] In the preferred technical scheme of the car seat, a clamping hole is formed in the top wall, and the car seat further includes a cover clamped on the clamping hole, and a restraint hole allowing the safety belt to pass therethrough is formed in the cover. The clamping hole facilitates the installation and removal of the cover, thereby improving the disassembly efficiency. In addition, the restraint hole formed in the cover provides a reliable fixing point for the safety belt.

[0009] In the preferred technical scheme of the car seat, the cover is made of plastic. The use of plastic material for the cover can reduce the friction coefficient between the safety belt and the cover, avoid damage to the safety belt, and thus prolong the service life of the safety belt.

[0010] In the preferred technical scheme of the car seat, a guide rod is arranged on the backrest framework, a pressing sleeve is arranged on the top wall, and an elastic member abutting against the backrest framework and the pressing sleeve is arranged on the guide rod. The above arrangement forms an elastic connection between the support bracket and the backrest framework, ensuring that the support bracket can smoothly move from the first position to the second position.

[0011] In the preferred technical scheme of the automobile seat, the elastic member is a coil spring.

[0012] In the preferred technical scheme of the automobile seat, the support bracket is made of steel material.

[0013] In the preferred technical scheme of the automobile seat, the support bracket is made by stamping process, which can improve the production efficiency and size accuracy, fully utilize the production raw materials and reduce the production cost.

[0014] In the preferred technical scheme of the automobile seat, the stamping process hole is arranged on the side wall.

[0015] In order to solve or improve the technical problem of poor safety of the automobile seat with zero gravity function in the prior art, the utility model also provides a vehicle. BRIEF DESCRIPTION OF DRAWINGS

[0027] In order to solve or improve the technical problem of poor safety of the car seat with zero gravity function in the prior art to some extent, the present application provides a car seat 100. The car seat 100 comprises: a backrest framework 110, the backrest framework 110 having a zero gravity position; a support bracket 120, the support bracket 120 being movably arranged at the upper part of the backrest framework 110 and having a first position away from the backrest framework 110 and a second position close to the backrest framework 110; and a safety belt, the safety belt being configured to be pressed on the support bracket 120, and when the backrest framework 110 is in the zero gravity position, the safety belt is configured to drive the support bracket 120 to move from the first position to the second position under the action of an external force.

[0028] Figure 1 is a structural schematic view of an embodiment of the utility model automobile seat. As Figure 1 indicated, in one or more embodiments, the utility model automobile seat 100 comprises a backrest framework 110, a support bracket 120 and a cushion framework 130 and the like components. Among them, the lower part of the backrest framework 110 is rotatably fixed on the cushion framework 130; the support bracket 120 is movably fixed on the upper part of the backrest framework 110.

[0029] As Figure 1 indicated, the cushion framework 130 can support the hip and leg of the passenger, help the passenger to keep the correct sitting posture, limit the body swing of the passenger, improve the stability and safety of riding. The cushion framework 130 can be adjusted under the control of a suitable driving mechanism (not identified in the figure) to realize the zero gravity function.

[0030] As Figure 1 indicated, in one or more embodiments, the utility model automobile seat 100 further comprises a slide rail 140 suitable for being fixed on the floor (not shown in the figure) of the vehicle, and the cushion framework 130 is slidably fixed on the slide rail 140 so as to adjust the front and back position of the cushion framework 130 on the floor. The sliding mode between the cushion framework 130 and the slide rail 140 can be manual adjustment or electric adjustment.

[0031] As Figure 1 indicated, in one or more embodiments, the utility model automobile seat 100 further comprises a leg rest 150 arranged on the side of the cushion framework 130 away from the backrest framework 110. The leg rest 150 can be expanded forward under the control of a suitable driving mechanism to increase the leg support area and further improve the comfort of riding.

[0032] Figure 2 is a structural schematic view of an embodiment of the backrest framework and the support bracket in the utility model automobile seat; Figure 3 is a partial structural schematic view of an embodiment of the backrest framework and the support bracket in the utility model automobile seat. As Figure 2 and Figure 3 indicated, in one or more embodiments, the backrest framework 110 comprises a horizontal rod 111 extending along the horizontal direction and a vertical rod 112 extending obliquely downward from both ends of the horizontal rod 111. The fixing mode between the horizontal rod 111 and the vertical rod 112 can be but not limited to welding, screwing and the like. The lower part of each vertical rod 112 is rotatably connected with the cushion framework 130. In this way, the whole backrest framework 110 can adjust the inclination angle under the control of a suitable driving mechanism (not identified in the figure) so as to switch between the normal position and the zero gravity position.

[0033] As Figures 1-3As shown, in one or more embodiments, the support bracket 120 is arranged on the upper part of the backrest frame 110 and located on the right side of the backrest frame 110 (based on...). Figure 3 (As shown in the diagram). The automobile seat 100 of this utility model also includes a seat belt (not shown in the figure). In this case, the fixing point of the seat belt above the backrest frame 110 is also located on the right side of the backrest frame 110, so that the seat belt can press against the support bracket 120. Alternatively, the support bracket 120 can also be arranged above the backrest frame 110 and located on the left side of the backrest frame 110. Accordingly, the fixing point of the seat belt above the backrest frame 110 is also located on the left side of the backrest frame 110, thereby ensuring that the seat belt can always press against the support bracket 120.

[0034] Figure 4 This is a front structural schematic diagram of an embodiment of the support bracket in a car seat according to the present invention; Figure 5 This is a schematic diagram of the rear structure of an embodiment of the support bracket in a car seat according to this utility model. Figures 3-5 As shown, in one or more embodiments, the support bracket 120 includes a top wall 121 and side walls 122 connected to each other. The side walls 122 extend downward from at least a portion of the circumferential edge of the top wall 121. The support bracket 120 may be made of a suitable metal material to give it good mechanical properties, such as steel. Preferably, the steel is high-strength steel, which gives it high rigidity and strength, preventing it from deforming under the pressure of the seat belt. In one or more embodiments, the support bracket 120 is manufactured by a stamping process, which can improve production efficiency and dimensional accuracy, make full use of raw materials, and reduce production costs.

[0035] like Figure 3 As shown, the top wall 121 is located at the upper part of the backrest frame 110. Specifically, the top wall 121 is located above the crossbar 111 of the backrest frame 110. See also... Figures 3-5In one or more embodiments, two clamping holes 1211 are formed on the top wall 121 and are spaced apart from each other along the left-right direction. Each clamping hole 1211 has a substantially rectangular shape. In addition, the automobile seat 100 further comprises a cover (not shown in the drawings). The cover is detachably clamped in the clamping hole 1211 of the top wall 121. A restraint hole is formed on the cover to allow the seat belt to pass therethrough. In this way, when the seat belt is tightened, the seat belt can transmit pressure to the top wall 121 through the cover without directly contacting the top wall 121. In one or more embodiments, the cover is made of plastic (such as ABS, PE, etc.) to reduce the friction between the seat belt and the cover, avoid damaging the seat belt, and thus prolong the service life of the seat belt. Alternatively, the number and shape of the clamping hole 1211 can be adjusted according to actual needs as long as they can be matched with the cover. For example, the number of clamping holes 1211 is set to one, three, etc.; the shape of the clamping hole 1211 is set to a circle, a square, etc.

[0036] As shown in Figures 3-5 In one or more embodiments, the side wall 122 comprises a first side wall 122a and a second side wall 122b connected to each other. The first side wall 122a extends downward from the circumferential edge of the right side of the top wall 121, and the second side wall 122b extends downward from the circumferential edge of the front side of the top wall 121. In other words, the top wall 121, the first side wall 122a and the second side wall 122b are substantially perpendicular to each other. In the assembled state, the first side wall 122a is opposite to the vertical rod 112 on the right side of the backrest framework 110, and the second side wall 122b is opposite to the horizontal rod 111 of the backrest framework 110. Alternatively, the side wall 122 only comprises one of the first side wall 122a and the second side wall 122b. Each side wall 122 is provided with a fixing hole 1221 extending in the vertical direction. Specifically, the first side wall 122a is provided with a first fixing hole 1221a, and the second side wall 122b is provided with a second fixing hole 1221b. Each fixing hole 1221 is provided with a fastener 123 for fixedly connecting the support bracket 120 and the backrest framework 110. Specifically, the first fixing hole 1221a is provided with a first fastener 123a, and the second fixing hole 1221b is provided with a second fastener 123b. As shown in Figure 3 In the assembled state, the first fastener 123a is located at the lower part of the first fixing hole 1221a, and the second fastener 123b is located at the lower part of the second fixing hole 1221b. At this time, the support bracket 120 is located at a first position away from the backrest framework 110, and the top wall 121 of the support bracket 120 and the horizontal rod 111 of the backrest framework 110 are spaced apart by a certain distance. When the seat belt applies a certain external force to the support bracket 120 (for example, when the vehicle collides), the seat belt can drive the support bracket 120 to move downward (as shown in Figure 3The first fastener 123a moves to the upper part of the first fixing hole 1221a, and the second fastener 123b moves to the upper part of the second fixing hole 1221b, while the top wall 121 moves toward the crossbar 111 near the backrest frame 110. Therefore, when the car seat 100 of this invention is in a zero-gravity state, the backrest frame 110 is in a backward-tilted zero-gravity position. At this time, even if a vehicle collision occurs, the seat belt can move downward with the passenger to a certain extent, ensuring that the seat belt always acts on the passenger's shoulder and does not cause lateral strangulation, thus improving the safety of the car seat 100.

[0037] See also Figures 3-5 In one or more embodiments, each sidewall 122 is further provided with a stamping process hole 1222. Specifically, one first stamping process hole 1222a is provided on the first sidewall 122a, while three second stamping process holes 1222b spaced apart from each other are provided on the second sidewall 122b. The provision of the stamping process holes 1222 ensures the processing accuracy of the stamping process. Alternatively, the number and arrangement of the stamping process holes can be adjusted according to actual needs.

[0038] like Figure 5 As shown, in one or more embodiments, a pressing sleeve 1212 is provided on the top wall 121. Specifically, based on Figure 5 As shown, the pressing sleeve 1212 extends vertically downward from the lower surface of the top wall 121. The pressing sleeve 1212 has a generally cylindrical shape, and a downward-opening receiving cavity (not shown in the figure) is formed inside the pressing sleeve 1212. Additionally, a guide rod 124 is provided on the backrest frame 110. Specifically, based on... Figure 5 As shown, the guide rod 124 extends approximately vertically. In the assembled state, the lower part of the guide rod 124 is fixed to the underside of the crossbeam of the backrest frame 110 by a mounting member 126. The mounting member 126 includes, but is not limited to, nuts and washers. An elastic element 125 is sleeved on the guide rod 124, and the elastic element 125 abuts against both the backrest fastener and the pressing sleeve 1212. Therefore, when the support bracket 120 moves from the first position to the second position under the pressure of the seat belt, the pressing sleeve 1212 can move towards the guide rod 124 and compress the elastic element 125, thereby converting part of the mechanical potential energy into the elastic potential energy of the elastic element 125, so that an elastic connection is formed between the support bracket 120 and the backrest frame 110, ensuring that the support bracket 120 can smoothly move from the first position to the second position. In one or more embodiments, the elastic element 125 is a helical spring, which has the characteristics of simple structure, easy processing, high energy efficiency, good resilience, and strong load capacity. Alternatively, the elastic element 125 may also take other suitable forms, such as rubber elastic elements.

[0039] In one or more embodiments, the utility model also provides a vehicle (not shown in the figure). The vehicle includes the car seat 100 described in any of the above embodiments.

[0040] So far, the technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the utility model is obviously not limited to these specific embodiments. Without deviating from the principles of the utility model, those skilled in the art can make equivalent changes or replacements to related technical features, and the technical schemes after these changes or replacements will fall within the protection scope of the utility model.
