[0034] With reference to Figure 1 and Figure 2 The present application provides a vehicle (not shown). The vehicle comprises a driver seat (not shown), a middle seat 200 and a car seat 100. The middle seat 200 is arranged between the driver seat and the car seat 100. The driver seat can be understood as a seat for a driver who drives the vehicle. The car seat 100 can be understood as a co-driver seat as commonly known in daily life. In a conventional vehicle, the driver seat and the co-driver seat are usually arranged with a co-instrument panel and an armrest box. The present application enables the front row of the vehicle to accommodate one more passenger by arranging the middle seat 200 between the driver seat and the co-driver seat. Considering that a conventional vehicle will have one of the passengers sitting separately from the other passengers when carrying three passengers, the vehicle of the present application enables all passengers to sit in the front row by arranging the middle seat 200, thereby improving the convenience of passenger communication and enhancing the passenger riding experience.

[0035] In some embodiments, the intermediate seat 200 comprises a backrest unit 202 and a seat unit 203. The backrest unit 202 and the seat unit 203 are pivotally connected. In this way, when the intermediate seat 200 does not need to be occupied by a passenger, the backrest unit 202 can be pivoted close to the seat unit 203, that is, the backrest unit 202 is folded up, so that the front space and the rear space in the vehicle interior are communicated, and the permeability of the passenger space in the vehicle interior is improved.

[0036] Further, the vehicle comprises a control system (not shown). In some embodiments, the side of the backrest unit 202 away from the seat unit 203 is provided with a sub-instrument panel (not shown). The sub-instrument panel is provided with an electric control unit (not shown). The electric control unit is electrically connected with the control system. In other words, the sub-instrument panel can be used as a control panel, and can also be unfolded to be used as the intermediate seat 200, so as to meet different needs of passengers and improve the satisfaction of passengers.

[0037] In order to improve the safety of the intermediate seat 200, the vehicle needs to provide a seat belt structure on the intermediate seat 200. Due to the limited space between the driver's seat and the car seat 100, it is difficult for the intermediate seat 200 to be provided with a skeleton of sufficient size and strength to ensure the protection strength of the seat belt structure when impacted. Therefore, the vehicle of the present application borrows the structure of the car seat 100 to provide safety protection for the intermediate seat 200.

[0038] The car seat 100 of the present application comprises a seat body 1. The seat body 1 comprises a pivotally connected seat part 11 and a backrest part 12, so that the passenger can adjust the angle between the seat part 11 and the backrest part 12, and improve the comfort of the seat. The backrest part 12 comprises an upper end 121 away from the seat part 11. The seat part 11 comprises a back surface 111, and opposite first and second side surfaces 112 and 113. The seat body 1 further comprises a first seat belt assembly 2 arranged on the seat body 1. The first seat belt assembly 2 comprises a first fixing unit 21 and a first connecting unit 22. The first fixing unit 21 is arranged close to the first side surface 112. The first connecting unit 22 is arranged on the second side surface 113. The first fixing unit 21 can be detachably connected with the first connecting unit 22. When the first fixing unit 21 and the first connecting unit 22 are connected, the first seat belt assembly 2 can form a connection in the plane of the width direction X and the height direction Z, so as to fix the passenger seated on the car seat 100 on the car seat 100. When the vehicle is impacted, the first seat belt assembly 2 can prevent the passenger from moving in the length direction Y, so as to prevent the passenger from being injured again.

[0039] The seat body 1 further comprises a second safety belt assembly 3 arranged on the seat body 1. The second safety belt assembly 3 comprises a second fixing unit 31. The second fixing unit 31 is arranged close to the second side surface 113. The intermediate seat 200 comprises a second connecting unit 201. The second connecting unit 201 is arranged on the side of the intermediate seat 200 away from the car seat 100. The second fixing unit 31 is detachably connected with the second connecting unit 201. When the second fixing unit 31 is connected with the second connecting unit 201, the cooperation between the second safety belt assembly 3 and the second connecting unit 201 can form a connection in the plane of the width direction X and the height direction Z on the intermediate seat 200, thereby fixing the passenger sitting on the intermediate seat 200 on the car seat 100.

[0040] The car seat 100 has a large size, and thus the skeleton structure has a greater strength than the skeleton strength of the intermediate seat 200. The present application arranges the second safety belt assembly 3 on the car seat 100 to improve the protection strength of the second safety belt assembly 3, thereby also improving the protection safety of the passenger sitting on the intermediate seat 200. In addition, since the size of the intermediate seat 200 in the width direction X is generally smaller than that of the car seat 100, arranging the second safety belt assembly 3 on the intermediate seat 200 can also cause the second safety belt assembly 3 to bring a sense of restraint and friction marks to the passenger, thereby affecting the comfort of the passenger. Therefore, the arrangement of the vehicle of the present application can provide a proper seating space for the passenger of the intermediate seat 200 when the passenger sits on the intermediate seat 200, and the second safety belt assembly 3 is farther away from the passenger, thereby improving the riding experience and comfort of the passenger.

[0041] Reference Figure 3 and Figure 4 The first fixing unit 21 comprises a first fixing end 211, a first winding end 212, and a first safety belt body 213. One end of the first safety belt body 213 is fixedly connected with the first fixing end 211, and the other end is wound on the first winding end 212. In this way, when the first safety belt assembly 2 is not needed, the first safety belt body 213 can be wound on the first winding end 212, thereby improving the neatness of the car seat 100. When the passenger uses the first safety belt assembly 2, the passenger can pull the first safety belt assembly 2 according to the needs, so that the first safety belt assembly 2 can fix the passenger on the car seat 100 with appropriate force.

[0042] In some embodiments, the first fixed end 211 is arranged on the first side 112. The first winding end 212 is arranged on the back 111 and close to the first fixed end 211. The first safety belt body 213 is also slidably connected with the upper end 121. When a passenger uses the first safety belt assembly 2, the passenger pulls the first safety belt body 213 in the direction of the first side 112 and connects the first safety belt body 213 and the first connecting unit 22. At this time, the first safety belt body 213 forms a triangle with the first fixed end 211, the upper end 121 and the first connecting unit 22 as the vertices in the plane of the height direction Z and the width direction X. The triangular structure can provide fixing and protection functions for the passenger at multiple positions, and can reduce the tightness of the passenger under the condition of the same fixing force, and improve the use experience of the passenger.

[0043] In fact, this embodiment arranges the first safety belt assembly 2 on the car seat 100 as a whole. In this way, when the passenger moves the seat body 1 in the length direction Y and rotates the seat body 1 around the height direction Z, the first safety belt assembly 2 can move together with the seat body 1, facilitating the movement adjustment of the seat body 1. Among them, the width direction X, the length direction Y and the height direction Z described above and below are perpendicular to each other.

[0044] It should be noted that the car seat 100 shown in the drawings is a framework structure. In fact, the car seat 100 also includes surface components such as soft cushions. The sliding connection between the first safety belt body 213 and the upper end 121 can be that the part connected with the first winding end 212 is arranged in the soft cushion, and then extends out of the soft cushion at the soft cushion of the upper end 121 through an opening, and the sliding connection with the upper end 121 is achieved through the opening. Alternatively, a structure allowing the first safety belt body 213 to pass through can also be arranged on the framework, and the present application does not limit this.

[0045] In other embodiments, the first winding end 212 is arranged in the body structure of the vehicle, and the first safety belt body 213 extends from the B pillar (not shown). When a passenger uses the first safety belt assembly 2, the first safety belt body 213 forms a triangle with the first fixed end 211, the B pillar and the first connecting unit 22 as the vertices in the plane of the height direction Z and the width direction X. This arrangement fixes the first safety belt assembly 2 and the body of the vehicle, improves the protection strength of the first safety belt assembly 2, and can also reduce the requirement for the strength of the car seat 100.

[0046] Similarly, the second fixing unit 31 includes a second fixing end 311, a second retractable end 312, and a second seat belt body 313. One end of the second seat belt body 313 is fixedly connected to the second fixing end 311, and the other end is retracted to the second retractable end 312. The second seat belt body 313 is also slidably connected to the upper end 121. The second fixing end 311 is located at the pivot position between the seat portion 11 and the backrest 12. The second retractable end 312 is located on the backrest 111. The second fixing end 311 and the second retractor are located near the second side 113.

[0047] Compared to the technical solution of placing the second fixing end 311 on the second side 113, placing the second fixing end 311 at the pivot position between the seat part 11 and the backrest 12 is advantageous for separating it from the first connecting unit 22, avoiding interference between the second seat belt body 313 and the first connecting unit 22 when the first seat belt assembly 2 and the second seat belt assembly 3 are used simultaneously. Furthermore, the pivot position of the second fixing end 311 between the seat part 11 and the backrest 12 allows for a certain distance between the second fixing end 311 and the second side 113, thus allowing passengers sitting in the middle seat 200 more legroom and greater comfort when wearing the second seat belt body 313.

[0048] It should be noted that the sliding connection between the second seat belt body 313 and the upper end 121 can also be that the part connected to the second roll-up end 312 is placed inside the soft pad, and then the soft pad at the upper end 121 extends out through the opening and is slidably connected to the upper end 121 through the opening.

[0049] like Figure 4 As shown, in some embodiments, the seat body 1 includes a fixing structure 13 disposed on the backrest 111. A portion of the first fixing unit 21 and a portion of the second fixing unit 31 are connected to the fixing structure 13. The following description will use an embodiment where the first roll-up end 212 and the second roll-up end 312 are respectively connected to the fixing structure 13 as an example.

[0050] The fixing structure 13 provides a robust rigid connection between the first roll retractor 212 and the second roll retractor 312. In the event of a collision, the first roll retractor 212 and the second roll retractor 312 remain connected to the seat body 1 via the fixing structure 13, preventing them from detaching and causing a failure of protection. Furthermore, the fixing structure 13 is located on the backrest 111 of the seat portion 11, therefore the first roll retractor 212 and the second roll retractor 312 are also located on the seat portion 11. Consequently, the backrest 12 can have a streamlined design and appearance, enhancing the aesthetics of the car seat 100.

[0051] In this embodiment, the first winding end 212 and the second winding end 312 can be connected with the seat part 11 and the fixed structure 13 at the same time, so as to further strengthen the connection strength. For example, even if the first winding end 212 or the second winding end 312 is separated from the seat part 11 after the vehicle is hit, it can still be connected with the fixed structure 13, so the first safety belt assembly 2 or the second safety belt assembly 3 still has a protective effect on the passenger.

[0052] The application is not limited to the arrangement of the fixed structure 13. For example, the fixed structure 13 can protrude from the first side surface 112, and the first fixed unit 21 is connected with the fixed structure 13 on the side of the first side surface 112 away from the second side surface 113. Those skilled in the art can arrange according to the space of the vehicle and the structure space inside the seat body 1. In some embodiments, the fixed structure 13 is arranged between the first side surface 112 and the second side surface 113. In other words, the first winding end 212 and the second winding end 312 are arranged between the first side surface 112 and the second side surface 113.

[0053] By such arrangement, the first winding end 212 and the second winding end 312 can be accommodated inside the seat body 1 in the width direction X. When the automobile seat 100 is installed in different vehicles, no space needs to be reserved for the second winding end 312 protruding from the second side surface 113 or the first winding end 212 protruding from the first side surface 112, improving the versatility of the automobile seat 100. In addition, such arrangement also makes the distance between the first winding end 212 and the upper end 121 and the distance between the second winding end 312 and the upper end 121 shortest, so the passenger can fully utilize the length of the first safety belt body 213 and the second safety belt body 313.

[0054] In some embodiments, the first fixed unit 21 and the second fixed unit 31 are connected to the side of the fixed structure 13 facing the first side surface 112. In other words, the first winding end 212 and the second winding end 312 can be accommodated inside the seat body 1 in the length direction Y. Such arrangement can reduce the size of the automobile seat 100 in the length direction Y, so as to provide a more spacious and comfortable seating space for the passengers in the rear row of the vehicle. In addition, such arrangement can also avoid the problem that the passengers are easy to kick the first fixed unit 21 and the second fixed unit 31 due to the protrusion of the fixed structure 13, thereby avoiding the injury of the passengers and reducing the service life of the first fixed unit 21 and the second fixed unit 31.

[0055] It is true that the skilled in the art can selectively set only the first fixing unit 21 on one side of the fixed structure 13 facing the first side 112 or only the second fixing unit 31 on one side of the fixed structure 13 facing the second side 113 according to the actual internal space of the automobile seat 100 and the internal space of the vehicle, and the present application does not limit this.

[0056] Further, the first fixing unit 21 and the second fixing unit 31 are arranged between the first side 112 and the second side 113, and are arranged on one side of the fixed structure 13 facing the first side 112. At this time, the first fixing unit 21 and the second fixing unit 31 can be completely hidden in the interior of the seat body 1, and the automobile seat 100 is convenient for moving forward and backward, rotating and other position changes.

[0057] Since the automobile seat 100 is provided with the first safety belt assembly 2 and the second safety belt assembly 3, when the intermediate seat 200 and the automobile seat 100 are both occupied by passengers, the impact load of the automobile seat 100 and the intermediate seat 200 is actually borne by the automobile seat 100. Therefore, the automobile seat 100 is difficult to provide sufficient protection for two passengers in the case of insufficient strength. Therefore, the automobile seat 100 of the present application is designed to enhance the strength of the frame structure.

[0058] Reference Figure 5 and Figure 6 The backrest part 12 comprises a backrest frame 122. In some embodiments, the backrest frame 122 comprises a main backrest beam 1221 extending along the height direction Z and a reinforcing backrest beam 1222. The main backrest beam 1221 is fixedly connected with the reinforcing backrest beam 1222, and a support space 1223 of the backrest frame 122 is formed between the main backrest beam 1221 and the reinforcing backrest beam 1222. The main backrest beam 1221 can be regarded as a backrest beam used by the automobile seat 100 of the conventional vehicle. The reinforcing backrest beam 1222 can be regarded as a backrest beam provided by the present application to improve the strength of the backrest frame 122. By setting the backrest frame 122 as a double-layer sheet metal structure, the strength of the backrest frame 122 can be improved, so that the backrest part 12 can bear the load brought by the passenger movement when the vehicle is impacted, and the protection performance of the first safety belt assembly 2 and the second safety belt assembly 3 is improved.

[0059] Furthermore, the backrest 12 also includes a backrest support 1224. The backrest support 1224 is disposed in the support space 1223 and is fixedly connected to the main backrest beam 1221 and the reinforcing backrest beam 1222, respectively. The backrest support 1224 supports the main backrest beam 1221 and the reinforcing backrest beam 1222 in the support space 1223, improving the resistance of the main backrest beam 1221 and the reinforcing backrest beam 1222 to deformation, further improving the strength of the backrest frame 122, thereby indirectly ensuring the protection of the passenger by the first seat belt assembly 2 and the second seat belt assembly 3.

[0060] exist Figure 6 In the illustrated embodiment, the backrest support 1224 is configured with its opening facing the seat portion 11. This configuration is for ease of manufacturing. The main backrest beam 1221, the reinforcing backrest beam 1222, and the backrest support 1224 are connected by welding. During welding, the main backrest beam 1221 and the reinforcing backrest beam 1222 can be welded together first. Figure 6 In the illustrated embodiment, the main backrest beam 1221 has a larger space facing the seat portion 11, which facilitates welding. Therefore, the backrest support 1224 is configured with its opening facing the seat portion 11. Admittedly, those skilled in the art can modify the opening direction of the backrest support 1224 according to the actual arrangement of the main backrest beam 1221, and this application does not limit this.

[0061] In some embodiments, the cross-section of the backrest frame 122 perpendicular to the height direction Z is I-shaped. The I-shaped design is small in size and high in strength. In addition, this design can also reduce the size of the backrest support 1224 in the width direction X, avoiding material waste and thus reducing production costs.

[0062] On the side of the reinforcing backrest beam 1222 closest to the seat portion 11, there is an angle α between the reinforcing backrest beam 1222 and the longitudinal direction Y. This arrangement allows passengers to be further away from the backrest frame 122 when sitting in the car seat 100, thus providing more seating space and improving the comfort of the car seat 100. If the angle α is too large, the distance between the reinforcing backrest beam 1222 and the main backrest beam 1221 will decrease, potentially reducing the reinforcement effect. If the angle α is too small, the reinforcing backrest beam 1222 will excessively encroach on the passenger's seating space. Therefore, after numerous calculation experiments by the inventors, an angle α between 40° and 50° can effectively balance seating comfort and reinforcement effect.

[0063] In some embodiments, the main backrest beam 1221 is provided with a reinforcing rib 1225 on the side away from the seat part 11. When the vehicle is hit, the passenger still moves forward, thus pulling the first and second safety belt assemblies 2 and 3 forward as well. The main backrest beam 1221 is subjected to a force in the length direction Y from the backrest part 12 towards the seat part 11, and the side of the main backrest beam 1221 away from the seat part 11 is subjected to a greater moment of force. By providing the reinforcing rib 1225 on this side, the strength of the main backrest beam 1221 on the side away from the seat part 11 can be improved, and the supporting strength of the main backrest beam 1221 can be further improved.

[0064] From another perspective, the design of the reinforcing rib 1225 can increase the cross-sectional area of the main backrest beam 1221 in the height direction Z, and also has the effect of improving the strength of the main backrest beam 1221. In addition, in some embodiments, the main backrest beam 1221 is also provided with a reinforcing structure 1226. This structure also has the effect of increasing the cross-sectional area, further improving the strength of the main backrest beam 1221, and is beneficial to bearing the increased load of the automotive seat 100 due to the provision of the double safety belt assemblies.

[0065] Reference Figure 7 and Figure 8 The seat part 11 comprises a seat skeleton 114. Similarly, the seat skeleton 114 comprises a main seat beam 1141 and a reinforcing seat beam 1142 extending in the length direction Y. The main seat beam 1141 and the reinforcing seat beam 1142 are fixedly connected and form a reinforcing space 1143 of the seat skeleton 114 between the main seat beam 1141 and the reinforcing seat beam 1142. The main seat beam 1141 can be regarded as a seat beam used by the automotive seat 100 of a conventional vehicle. The reinforcing seat beam 1142 can be regarded as a seat beam provided by the present application to improve the strength of the backrest skeleton 122. By providing the backrest skeleton 122 as a double-layer sheet metal structure, the strength of the backrest skeleton 122 can be improved, so that when the vehicle is hit, the backrest part 12 can bear the load brought by the movement of the passenger, and the protection performance of the first and second safety belt assemblies 2 and 3 can be improved.

[0066] In some embodiments, the seat skeleton 114 further comprises a seat support 1144. The seat support 1144 is arranged in the reinforcing space 1143 and is fixedly connected to the main seat beam 1141 and the reinforcing seat beam 1142, respectively. When the vehicle is hit, the passenger tends to move forward in the length direction Y. The first and second safety belt bodies 213 and 313 need to pull the passenger in the length direction Y, so the seat part 11 is also subjected to a force in the length direction Y. The seat support 1144 can "fill" the reinforcing space 1143 to some extent, thereby improving the load resistance of the seat skeleton 114 when hit, so that the seat skeleton 114 does not deform and cause the protection of the first and second safety belt assemblies 2 and 3 to fail.

[0067] Furthermore, the reinforcing seat beam 1142 is provided with a recessed structure 1145 on the side away from the main seat beam 1141. The side of the recessed structure 1145 facing the main seat beam 1141 is the welding surface with the seat support member 1144. By providing the recessed structure 1145, the welding position and the non-welding position are separated, thus facilitating the welding of the seat support member 1144 and the reinforcing seat beam 1142, and simplifying assembly.

[0068] In some embodiments, the thickness of the reinforcing seat beam 1142 is greater than the thickness of the main seat beam 1141. As mentioned above, the main seat beam 1141 is a conventional seat beam. This application further improves the strength of the seat frame 114 by increasing the thickness of the reinforcing seat beam 1142 without modifying the arrangement of the main seat beam 1141. Therefore, the seat frame 114 of this application can be used in existing conventional vehicle seat beams, and its processing is simple. The thickness of the reinforcing seat beam 1142 and the seat support 1144 can be within the range of 2mm-4mm, thereby improving strength while avoiding excessive space occupation.

[0069] like Figure 8 As shown, in Figure 8 From the perspective of the figure, the upper dimension of the seat frame 114 is larger than the lower dimension. This is because when a passenger sits in the car seat 100, they are actually sitting under the seat frame 114 shown in the figure. Therefore, the lower dimension of the seat frame 114 is smaller, which can provide a comfortable seating space for the passenger. The increased upper dimension of the seat frame 114 can improve the strength of the seat frame 114 to prevent deformation during an impact.

[0070] Similar to the main backrest beam 1221, the main seat beam 1141 is also provided with a reinforcing structure 1146. This structure can increase the cross-sectional area, further improve the strength of the main seat beam 1141, and help to withstand the increased load on the car seat 100 due to the installation of the dual seat belt assembly.

Those skilled in the art to which this application pertains may make various modifications, additions, or use similar methods to replace the described specific embodiments, without departing from the spirit of this application or exceeding the scope defined by the appended claims.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
