Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile seat structure, in particular to an automobile rear seat and an automobile with the automobile rear seat. BACKGROUND

[0002] The wheelbase of some models on the market is small, and the maximum sliding stroke of the rear seat of the automobile is generally 130mm (of course, the maximum sliding stroke of the seat designed for different models is slightly different). When installing the rear seat of the automobile, the seat needs to be slid to the front end before the rear end of the seat can be installed into the rear space of the seat. Since the maximum sliding stroke of the seat of some short wheelbase models is short, the seat cannot be slid to the designed front end to install the rear end of the seat. In order to solve this problem, the seat can be slid at least 210mm forward when installed, that is, the maximum sliding stroke when installed is at least 210mm, and the maximum sliding stroke when used normally needs to be less than 210mm (for example, 130mm as described above, and the maximum sliding stroke is too long which may cause harm to the passengers), that is, the seat has double sliding strokes.

[0003] The automobile seat with double sliding strokes on the market at present, such as the "easy-to-enter seat slide rail stroke switching mechanism and automobile seat containing the same" disclosed in Chinese Invention Patent CN110466396A, has a stroke blocking piece connected to the lower slide rail, a seat movable flap hinged to the upper slide rail, and a stroke adjusting piece connected to the seat movable flap. When the seat is in a seating state, the stroke adjusting piece can abut against the blocking piece to make the seat have a first sliding stroke; when the seat is in an easy-to-enter state, the seat movable flap is turned up, and the stroke adjusting piece is separated from the blocking piece to make the seat have a second sliding stroke. The 210mm sliding stroke of the seat is only used when the seat is installed, and the function of the easy-to-enter rear seat is redundant, which will not be used when the seat is used normally. At the same time, the slide rail stroke switching mechanism of the seat is complex in structure and high in cost, and the similar structure is not cost-effective, and the cost exceeds the budget.

[0049] First embodiment

[0050] As Figures 1 to 5 shown, the first embodiment of the present application provides a rear seat 1 of an automobile, which aims to solve the problem that when the rear seat 1 of the automobile is installed into the body of the automobile, due to the short maximum sliding stroke designed for the rear seat 1 of the automobile of some short wheelbase models, after the rear seat 1 of the automobile slides to the front end, the rear end mounting bolt (not shown in the figure, the bolt for fixing the rear end of the rear seat 1 of the automobile to the body of the automobile) cannot be installed into the rear space of the rear seat 1 of the automobile.

[0051] Specifically, as Figure 1 and Figure 2 shown, the rear seat 1 of the automobile includes a backrest 11 and a cushion 12 connected to each other. In this embodiment, the number of backrests 11 is two, which are a 60% backrest 111 and a 40% backrest 112 (wherein 60% and 40% refer to the ratio of the width of the backrest 111 and the backrest 112 to the width of the rear seat, respectively), and the number of cushions 12 is two, which are a 60% cushion 121 and a 40% cushion 122 (wherein 60% and 40% refer to the ratio of the width of the cushion 121 and the cushion 122 to the width of the rear seat, respectively). The 60% backrest 111 is rotatably connected to the 60% cushion 121, and the 40% backrest 112 is rotatably connected to the 40% cushion 122. The rotatable connection and angle adjustment between the backrest 11 and the cushion 12 are achieved through an angle adjustment mechanism 8.

[0052] Further, as Figure 1 and Figure 2 shown, a sliding mechanism 2 is arranged below the cushion 12. The sliding mechanism 2 includes an upper sliding rail 21 and a lower sliding rail 22. The upper sliding rail 21 is slidable along the lower sliding rail 22. The upper sliding rail 21 is fixedly connected to the bottom of the cushion 12, and the lower sliding rail 22 is fixedly connected to the body of the automobile. The sliding mechanism 2 controls its sliding and locking through an unlocking mechanism 9 to achieve the forward and backward sliding and locking of the rear seat 1 of the automobile. It should be noted that, as Figure 1 and Figure 2 shown, in this embodiment, the direction S in which the rear seat 1 of the automobile is slid towards the steering wheel (not shown in the figure) is defined as the front direction.

[0053] In this embodiment, one pair of sliding mechanisms 2 is arranged on the left and right sides of the bottom of the 60% cushion 121 and the bottom of the 40% cushion 122, respectively, to ensure the stability of the forward and backward sliding of the rear seat 1 of the automobile.

[0054] Further, as shown in Figures 3 to 5 the first lower stop point 5 and the first upper stop point 4 correspond to each other in front and back, and the first lower stop point 5 is located in front of the first upper stop point 4; the second lower stop point 7 and the second upper stop point 6 correspond to each other in front and back, and the second lower stop point 7 is located in front of the second upper stop point 6; and the distance between the second upper stop point 6 and the second lower stop point 7 is less than the distance between the first upper stop point 4 and the first lower stop point 5.

[0055] When the upper slide rail 21 slides along the lower slide rail 22 and one of the second upper stop point 6 and the second lower stop point 7 is not installed on the sliding mechanism 2, the upper slide rail 21 drives the first upper stop point 4 to move towards the first lower stop point 5, and when the first upper stop point 4 abuts against the first lower stop point 5, the automobile rear seat 1 has a first maximum sliding stroke.

[0056] When the upper slide rail 21 slides along the lower slide rail 22 and both the second upper stop point 6 and the second lower stop point 7 are installed on the sliding mechanism 2, the upper slide rail 21 drives the second upper stop point 6 to move towards the second lower stop point 7, and when the second upper stop point 6 abuts against the second lower stop point 7, the automobile rear seat 1 has a second maximum sliding stroke. The second maximum sliding stroke is less than the first maximum sliding stroke.

[0057] Specifically, the first maximum sliding stroke is the stroke used by the automobile rear seat 1 when it is installed in a vehicle, and in this stroke, the second upper stop point 6 and / or the second lower stop point 7 are not installed on the sliding mechanism 2, the rear space of the automobile rear seat 1 is relatively large, and the rear end mounting bolt is convenient to install; in this embodiment, the first maximum sliding stroke is 210 mm.

[0058] The second maximum sliding stroke is the stroke used by the automobile rear seat 1 when a user normally sits in it after the automobile rear seat 1 is installed in the vehicle. When the second upper stop point 6 and / or the second lower stop point 7 are installed on the sliding mechanism 2 after the automobile rear seat 1 is installed in the vehicle to shorten the maximum sliding stroke of the automobile rear seat 1, the maximum distance that the automobile rear seat 1 can slide is relatively small in this stroke, and the personal safety of the user can be ensured; in this embodiment, the second maximum sliding stroke is 130 mm.

[0059] Further, as shown in Figures 3 to 5 In this embodiment, the upper slide rail 21 includes an upper slide rail body 23 and an upper support 24, the upper support 24 is fixedly connected to the upper slide rail body 23 and located above the upper slide rail body 23; and the lower slide rail 22 includes a lower slide rail body 25 and a lower support 26, the lower support 26 is fixedly connected to the lower slide rail body 25 and located below the lower slide rail body 25.

[0060] Specifically, in the present embodiment, the upper support 24 is fixedly connected with the top of the upper slide rail body 23, and the bottom of the seat cushion 12 is fixedly connected with the upper support 24 and the upper slide rail body 23 at the same time; the lower support 26 is fixedly connected with the bottom of the lower slide rail body 25, and the lower support 26 is fixedly connected with the body of the automobile. The upper slide rail body 23 can slide along the lower slide rail body 25, and the upper support 24 can slide along the lower support 26. The upper support 24 and the lower support 26 can improve the bearing strength of the lifting and sliding mechanism 2, and at the same time, reduce the bearing load of the upper slide rail body 23 and the lower slide rail body 25.

[0061] Of course, in other embodiments, the upper support 24 and the lower support 26 can be omitted, and the upper slide rail body 23 is directly fixedly connected with the seat cushion 12, and the lower slide rail body 25 is directly fixedly connected with the body of the automobile.

[0062] Further, the upper slide rail body 23 is a reverse "U" shaped structure, and the upper slide rail body 23 comprises a first top wall 231 and two first side walls 232 respectively downwardly extended from opposite sides of the first top wall 231, and the bottom of the first side wall 232 is outwardly folded to form a first outwardly folded edge 233. The lower slide rail body 25 is a "U" shaped structure, and the lower slide rail body 25 comprises a first bottom wall 251 and two first side plates 252 respectively upwardly extended from opposite sides of the first bottom wall 251, and the top of the first side plate 252 is inwardly folded to form a first inwardly folded edge 253.

[0063] Specifically, when the upper slide rail body 23 slides along the lower slide rail body 25, the bottom of the upper slide rail body 23 is in contact with the first bottom wall 251 of the lower slide rail body 25, and by arranging the first outwardly folded edge 233 on the bottom of the upper slide rail body 23, the first outwardly folded edge 233 is in contact with the first bottom wall 251 of the lower slide rail body 25, and the first outwardly folded edge 233 can slide along the first bottom wall 251 of the lower slide rail body 25, so that the upper slide rail body 23 can more smoothly slide along the lower slide rail body 25.

[0064] Further, the first outwardly folded edge 233 and the first inwardly folded edge 253 are mutually buckled and the first outwardly folded edge 233 can slide along the first inwardly folded edge 253. The first outwardly folded edge 233 and the first inwardly folded edge 253 are mutually buckled, which can prevent the upper slide rail body 23 and the lower slide rail body 25 from being separated, thereby avoiding the situation that the automobile rear seat 1 is tilted forward and backward or turned over left and right during the sliding process or normal sitting.

[0065] Further, as shown in FIG. 1, the upper support 24 comprises a first support 241 and a second support 242, and the first support 241 and the second support 242 are respectively fixedly connected with the top of the upper slide rail body 23. The first support 241 and the second support 242 are respectively fixedly connected with the seat cushion 12. Figures 3 to 5As shown, the upper support 24 comprises a second top wall 241 and two second side walls 242 extending downwardly from opposite sides of the second top wall 241, and the bottom of the second side wall 242 is inwardly folded to form a second inward flange 243. The lower support 26 comprises a second bottom wall 261 and two second side plates 262 extending upwardly from opposite sides of the second bottom wall 261, and the top of the second side plate 262 is outwardly folded to form a second outward flange 263.

[0066] In particular, when the upper support 24 slides along the lower support 26, the inner surface of the second side wall 242 is in contact with the top of the second side plate 262, and by providing the second outward flange 263 on the top of the second side plate 262, the inner surface of the second side wall 242 is in contact with the second outward flange 263, and the inner surface of the second side wall 242 can slide along the second outward flange 263, so that the upper support 24 can more smoothly slide along the lower support 26.

[0067] Further, the second inward flange 243 and the second outward flange 263 are mutually engaged and the second inward flange 243 can slide along the second outward flange 263. The mutual engagement of the second inward flange 243 and the second outward flange 263 can prevent the upper support 24 and the lower support 26 from being separated, and further avoid the situation that the rear seat 1 of the car tilts forward and backward or turns over left and right during sliding or normal seating, so as to ensure the personal safety of the user.

[0068] In the present embodiment, the first upper stop point 4 is provided on the upper support 24, the second upper stop point 6 is provided on the upper slide rail body 23, the first lower stop point 5 is provided on the lower support 26, and the second lower stop point 7 is provided on the lower slide rail body 25.

[0069] Further, in the present embodiment, the first upper stop point 4 is formed by the front end of the second inward flange 243, the first lower stop point 5 is protrudingly formed on the front end of the second outward flange 263, the second upper stop point 6 is installed on the first top wall 231, and the second lower stop point 7 is installed on the first bottom wall 251.

[0070] In the present embodiment, the first lower stop point 5 is only provided on the second outward flange 263 of one of the second side plates 262. Of course, in other embodiments, the first lower stop point 5 can be provided on the second outward flanges 263 of both of the second side plates 262, which is not limited herein.

[0071] In the present embodiment, the first lower stop point 5 is protrudingly formed downwardly by the front end of the second outward flange 263. Of course, in other embodiments, the first lower stop point 5 can be protrudingly formed outwardly or upwardly by the front end of the second outward flange 263, which is not limited herein.

[0072] In the embodiment, the top of the upper slide rail body 23 is provided with a first through hole 234, the second upper stop point 6 is arranged in the first through hole 234, and the second upper stop point 6 extends downward from the top wall of the upper slide rail body 23. The bottom of the lower slide rail body 25 is provided with a second through hole 254, the bottom of the lower support 26 is provided with a third through hole 267, the second through hole 254 and the third through hole 267 correspond to each other and are both located in front of the first through hole 234, and the second lower stop point 7 is arranged in the second through hole 254 and the third through hole 267 in a penetrating manner, and the second lower stop point 7 extends upward from the bottom wall of the lower slide rail body 25. The second lower stop point 7 can abut against the second upper stop point 6, that is, the second lower stop point 7 is located on the movement path of the second upper stop point 6.

[0073] Preferably, the first through hole 234, the second through hole 254 and the third through hole 267 are all located on the same axis in the sliding direction of the upper slide rail body 23.

[0074] Preferably, in the embodiment, the second lower stop point 7 is a bolt, and the second upper stop point 6 is another rigid object. Before the automobile rear seat 1 is installed in the automobile, the second upper stop point 6 is pre-installed on the upper slide rail body 23, and at this time, the second lower stop point 7 has not been installed on the lower slide rail body 25; after the automobile rear seat 1 is installed in the automobile, the second lower stop point 7 is then installed on the lower slide rail body 25, and then the second lower stop point 7 is fixed on the lower slide rail body 25 by means of a nut or welding. Of course, in other embodiments, the second upper stop point 6 can be a bolt, and the second lower stop point 7 can be another rigid object. Before the automobile rear seat 1 is installed in the automobile, the second lower stop point 7 is pre-installed on the lower slide rail body 25, and at this time, the second upper stop point 6 has not been installed on the upper slide rail body 23; after the automobile rear seat 1 is installed in the automobile, the second upper stop point 6 is then installed on the upper slide rail body 23, and then the second upper stop point 6 is fixed on the upper slide rail body 23 by means of a nut or welding. It is easy to think that the second upper stop point 6 and the second lower stop point 7 can also have other forms and structures, which are not limited herein.

[0075] As shown in FIG. 1, Figures 6 to 8 In another embodiment, the second upper stop point 6 and the second lower stop point 7 are both bolts. Before the automobile rear seat 1 is installed in the automobile, one bolt is pre-installed on the upper slide rail body 23 or the lower slide rail body 25; after the automobile rear seat 1 is installed in the automobile, the other bolt is then installed. Or, before the automobile rear seat 1 is installed in the automobile, no bolt is installed on the upper slide rail body 23 and the lower slide rail body 25; after the automobile rear seat 1 is installed in the automobile, the two bolts are then installed on the upper slide rail body 23 and the lower slide rail body 25, respectively, which are not limited herein.

[0076] The mounting sequence of the automobile rear seat 1 provided by the embodiment is as follows: the automobile rear seat 1 is placed in the vehicle body, when the rear end vehicle mounting bolt is mounted, the second through hole 254 and the third through hole 267 have not yet mounted the second lower stop point 7, the first upper stop point 4 can abut against the first lower stop point 5, that is, the automobile rear seat 1 has a first maximum sliding stroke, at this time, the automobile rear seat 1 is slid to the most front end, and the rear space of the automobile rear seat 1 can be conveniently accessed to mount the rear end vehicle mounting bolt; when the rear end vehicle mounting bolt is mounted, the second lower stop point 7 is mounted in the second through hole 254 and the third through hole 267, the second lower stop point 7 can abut against the second upper stop point 6, that is, the automobile rear seat 1 has a second maximum sliding stroke, and since the second maximum sliding stroke is less than the first maximum sliding stroke, the original first maximum sliding stroke can be inhibited, that is, when the second lower stop point 7 abuts against the second upper stop point 6, there is still a distance between the first upper stop point 4 and the first lower stop point 5, that is, the first upper stop point 4 has not yet abutted against the first lower stop point 5.

[0077] The automobile rear seat 1 provided by the embodiment has the first maximum sliding stroke by abutting the first upper stop point 4 against the first lower stop point 5, when the automobile rear seat 1 is located at the most front end of the first maximum sliding stroke, the rear space of the automobile rear seat 1 can be easily accessed to mount the rear end vehicle mounting bolt. After the rear end vehicle mounting bolt is mounted, the second lower stop point 7 is mounted, the second lower stop point 7 can abut against the second upper stop point 6, so that the automobile rear seat 1 has a second maximum sliding stroke, and the second maximum sliding stroke is less than the first maximum sliding stroke, that is, the maximum sliding stroke of the automobile rear seat 1 is shortened, and the safety of the user is ensured. Meanwhile, the installation position of the second lower stop point 7 can be adjusted to change the second maximum sliding stroke, so as to be suitable for different vehicle models.

[0078] As the background technology of the Chinese invention patent CN110466396A, in order to realize the double sliding stroke, the patent needs to additionally increase the stroke blocking piece, the stroke adjusting piece, the seat movable edge plate and the triggering structure on the automobile seat, and the embodiment only needs to increase two parts of the second lower stop point 7 and the second upper stop point 6, and the cost is reduced by about 85% compared with the prior art.

[0079] The embodiment only needs to additionally increase two parts of the second lower stop point 7 and the second upper stop point 6 to realize the double sliding stroke of the automobile rear seat 1, which not only has a simple structure, reliable function and convenient installation, but also saves the installation time of parts, reduces the space occupied by parts, and reduces the production cost due to low cost of parts.

[0080] Second embodiment

[0081] As Figure 9 and Figure 10As shown, the second embodiment of the application provides the automobile rear seat 1 which is basically the same as the first embodiment, and the difference lies in the different installation position of the second lower stop point 7. Meanwhile, the second upper stop point 6 and the first upper stop point 4 are the same stop point in the embodiment.

[0082] Specifically, in the embodiment, the first upper stop point 4 and the second upper stop point 6 are both arranged on the upper support 24, and the first lower stop point 5 and the second lower stop point 7 are both arranged on the lower support 26.

[0083] In the embodiment, the first upper stop point 4 and the second upper stop point 6 are the same stop point and are formed by the front end of the second inner flange 243, the first lower stop point 5 is protrudingly formed on the front end of the second outer flange 263, and the second lower stop point 7 is installed on the second side plate 262 and located behind the first lower stop point 5.

Of course, in other embodiments, each of the second side plates 262 can be provided with a fourth through hole 268, and one second lower stop point 7 is installed in each fourth through hole 268, which is not limited herein.

[0085] The installation sequence of the automobile rear seat 1 provided by the embodiment is as follows: the automobile rear seat 1 is placed in the vehicle body, when the rear end mounting bolt is installed, the second lower stop point 7 has not been installed in the fourth through hole 268 at this time, the first upper stop point 4 can abut against the first lower stop point 5, that is, the automobile rear seat 1 has a first maximum sliding stroke, at this time, the automobile rear seat 1 is slid to the front end, and the rear space of the automobile rear seat 1 can be conveniently accessed to install the rear end mounting bolt. When the installation of the rear end mounting bolt is completed, the second lower stop point 7 is installed in the fourth through hole 268, the second lower stop point 7 can abut against the second upper stop point 6, that is, the automobile rear seat 1 has a second maximum sliding stroke, and since the second maximum sliding stroke is smaller than the first maximum sliding stroke, the original first maximum sliding stroke can be inhibited, that is, when the second lower stop point 7 abuts against the second upper stop point 6, there is still a distance between the first upper stop point 4 and the first lower stop point 5, that is, the first upper stop point 4 has not abutted against the first lower stop point 5.

[0086] The other settings of the embodiment are the same as those of the first embodiment, which are not described herein.

[0087] Third Embodiment

[0088] As Figure 11 and Figure 12As shown, the third embodiment of the application provides a rear seat 1 of a vehicle which is substantially the same as the first embodiment, and the difference is that the upper slide rail 21 does not include the upper support 24, and the lower slide rail 22 does not include the lower support 26. Meanwhile, the forms and installation positions of the first upper stop point 4, the first lower stop point 5, the second upper stop point 6 and the second lower stop point 7 are different from those of the first embodiment.

[0089] Specifically, in the embodiment, the upper slide rail 21 includes an upper slide rail body 23, and the lower slide rail 22 includes a lower slide rail body 25. The upper slide rail body 23 is fixedly connected with the bottom of the seat cushion 12, and the lower slide rail body 25 is fixedly connected with the body of the vehicle. The upper slide rail body 23 is slidable along the lower slide rail body 25.

[0090] The upper slide rail body 23 is in the form of an inverted "U", and includes a first top wall 231 and two first side walls 232 which are respectively formed by extending downward from opposite sides of the first top wall 231. The bottom of each first side wall 232 is outwardly folded to form a first outwardly folded edge 233.

[0091] The lower slide rail body 25 is in the form of a "U", and includes a first bottom wall 251 and two first side plates 252 which are respectively formed by extending upward from opposite sides of the first bottom wall 251. The top of each first side plate 252 is inwardly folded to form a first inwardly folded edge 253.

[0092] In the embodiment, the first upper stop point 4 is protruded from the first side wall 232, the second upper stop point 6 is installed on the first side wall 232 and located in front of the first upper stop point 4, and the first lower stop point 5 and the second lower stop point 7 are the same stop point and protruded from the top of the first side plate 252.

[0093] Specifically, in the embodiment, the first upper stop point 4 is protruded from the outer surface of the first side wall 232, and the first lower stop point 5 and the second lower stop point 7 are protruded from the top of the first side plate 252.

[0094] In the embodiment, the first upper stop point 4 is arranged on only one of the first side walls 232, and the first lower stop point 5 and the second lower stop point 7 are arranged on only one of the first side plates 252. Of course, in other embodiments, the first upper stop point 4 can be arranged on both of the first side walls 232, and the first lower stop point 5 and the second lower stop point 7 can be arranged on both of the first side plates 252, which are not limited herein.

[0095] In the embodiment, the fifth through hole 236 is arranged on the first side wall 232 and located in front of the first upper stop point 4, and the second upper stop point 6 is installed in the fifth through hole 236 and protruded from the outer surface of the first side wall 232.

[0096] In this embodiment, a fifth through hole 236 is provided only on the first sidewall 232 on the side where the first upper stop point 4 is located. Of course, in other embodiments, both first sidewalls 232 may be provided with a fifth through hole 236, and a second upper stop point 6 may be installed in the fifth through hole 236 of each first sidewall 232. This is not limited here.

[0097] The installation sequence of the rear seat 1 provided in this embodiment is as follows: The rear seat 1 is placed inside the vehicle body. When installing the rear mounting bolts, the second upper stop 6 is not yet installed in the fifth through hole 236. The first upper stop 4 can abut against the first lower stop 5, meaning the rear seat 1 has a first maximum sliding travel. At this time, the rear seat 1 is slid to its foremost position, allowing easy access to the rear space of the rear seat 1 to install the rear mounting bolts. After the rear mounting bolts are installed, the second upper stop 6 is installed in the fifth through hole 236. The second upper stop 6 can abut against the second lower stop 7, meaning the rear seat 1 has a second maximum sliding travel. Since the second maximum sliding travel is less than the first maximum sliding travel, it can suppress the original first maximum sliding travel. That is, when the second lower stop 7 abuts against the second upper stop 6, there is still a distance between the first upper stop 4 and the first lower stop 5, meaning the first upper stop 4 has not yet abutted against the first lower stop 5.

[0098] Compared to the first embodiment, this embodiment has a simpler structure, fewer parts, lower cost, and easier installation.

[0099] The other settings in this embodiment are the same as in the first embodiment, and will not be repeated here.

[0100] Fourth embodiment

[0101] like Figure 13 and Figure 14 As shown, the rear seat 1 of the automobile provided in the fourth embodiment of the present invention is largely the same as that in the third embodiment. The upper slide rail 21 does not include the upper bracket 24, and the lower slide rail 22 does not include the lower bracket 26. The difference lies in the different structures of the upper slide rail body 23 and the lower slide rail body 25. At the same time, the forms and installation positions of the first upper stop point 4, the first lower stop point 5, the second upper stop point 6 and the second lower stop point 7 are different.

[0102] Specifically, in this embodiment, the upper slide rail 21 includes an upper slide rail body 23, and the lower slide rail 22 includes a lower slide rail body 25. The upper slide rail body 23 is directly fixedly connected to the bottom of the seat cushion 12, and the lower slide rail body 25 is directly fixedly connected to the vehicle body. The upper slide rail body 23 can slide along the lower slide rail body 25.

[0103] The upper slide rail body 23 is in an inverted "U" shape, and comprises a first top wall 231 and two first side walls 232 respectively extending downward from opposite sides of the first top wall 231, and the bottom of each first side wall 232 is outwardly folded to form a first outwardly folded edge 233.

[0104] The lower slide rail body 25 is in a "U" shape, and comprises a first bottom wall 251 and two first side plates 252 respectively extending upward from opposite sides of the first bottom wall 251, and the top of each first side plate 252 is inwardly folded to form a first inwardly folded edge 253.

[0105] In the present embodiment, a step 2330 is formed on the first outwardly folded edge 233, the first upper stop point 4 and the second upper stop point 6 are the same stop point and are formed by the step 2330, the first lower stop point 5 is formed by protruding from the inner side of the first side plate 252, and the second lower stop point 7 is installed on the first side plate 252 and located behind the first lower stop point 5.

[0106] Specifically, in the present embodiment, the front half of the first outwardly folded edge 233 is lower than the back half to form the step 2330. The first lower stop point 5 is a cutout piece formed by stamping on the first side plate 252 and integrated with the first side plate 252, and the first lower stop point 5 is inclined and folded toward the inner side of the first side plate 252.

[0107] In the present embodiment, the first lower stop point 5 is only provided on one of the first side plates 252. Of course, in other embodiments, the first lower stop point 5 can also be provided on both of the first side plates 252, which is not limited herein.

[0108] In the present embodiment, the sixth through hole 257 is provided on one of the first side plates 252, and the second lower stop point 7 is installed in the sixth through hole 257 and protrudes inwardly from the inner side wall of the first side plate 252. Of course, in other embodiments, the sixth through hole 257 can also be provided on both of the first side plates 252, and one second lower stop point 7 is installed in the sixth through hole 257 of each first side plate 252, which is not limited herein.

[0109] The installation sequence of the rear seat 1 provided in this embodiment is as follows: The rear seat 1 is placed inside the vehicle body. When installing the rear mounting bolts, the second lower stop 7 is not yet installed in the sixth through hole 257, and the step 2330 can abut against the first lower stop 5. This means the rear seat 1 has a first maximum sliding travel. At this time, the rear seat 1 is slid to its foremost position, allowing easy access to the rear space of the rear seat 1 to install the rear mounting bolts. After the rear mounting bolts are installed, the second lower stop 7 is installed in the sixth through hole 257. The second lower stop 7 abuts against the step 2330, meaning the rear seat 1 has a second maximum sliding travel. Since the second maximum sliding travel is less than the first maximum sliding travel, it can suppress the original first maximum sliding travel. That is, when the second lower stop 7 abuts against the second upper stop 6, there is still a distance between the first upper stop 4 and the first lower stop 5; that is, the first upper stop 4 has not yet abutted against the first lower stop 5.

[0110] The other settings in this embodiment are the same as in the third embodiment, and will not be repeated here.

[0111] Fifth embodiment

[0112] like Figure 15 and Figure 16 As shown, the rear seat 1 of the automobile provided in the fifth embodiment of the present invention is largely the same as that in the third embodiment. The upper slide rail 21 does not include the upper bracket 24, and the lower slide rail 22 does not include the lower bracket 26. The difference lies in the installation positions of the first upper stop point 4, the first lower stop point 5, the second upper stop point 6, and the second lower stop point 7.

[0113] Specifically, in this embodiment, the upper slide rail 21 includes an upper slide rail body 23, and the lower slide rail 22 includes a lower slide rail body 25. The upper slide rail body 23 is directly fixedly connected to the bottom of the seat cushion 12, and the lower slide rail body 25 is directly fixedly connected to the vehicle body. The upper slide rail body 23 can slide along the lower slide rail body 25.

[0114] The upper slide rail body 23 has an inverted "U" shaped structure. The upper slide rail body 23 includes a first top wall 231 and two first side walls 232 extending downward from opposite sides of the first top wall 231. The bottom of the first side wall 232 is folded outward to form a first outward flange 233.

[0115] The lower slide rail body 25 has a "U" shaped structure. The lower slide rail body 25 includes a first bottom wall 251 and two first side plates 252 extending upward from opposite sides of the first bottom wall 251. The top of the first side plate 252 is folded inward to form a first inner flange 253.

[0116] In the embodiment, the first upper stop point 4 and the second upper stop point 6 are arranged on the first top wall 231, and the second upper stop point 6 is located in front of the first upper stop point 4. The first lower stop point 5 and the second lower stop point 7 are the same stop point and arranged on the first bottom wall 251.

[0117] In the embodiment, the seventh through hole 237 and the eighth through hole 238 are arranged in sequence from back to front on the first top wall 231.

[0118] Preferably, the seventh through hole 237, the eighth through hole 238, and the ninth through hole 258 are located on the same axis in the sliding direction of the upper slide rail body 23.

[0119] The mounting sequence of the automobile rear seat 1 provided by the embodiment is as follows: the automobile rear seat 1 is placed in the vehicle body. When the rear end mounting bolt is mounted, the second upper stop point 6 is not arranged in the eighth through hole 238. The first upper stop point 4 can abut against the first lower stop point 5, that is, the automobile rear seat 1 has a first maximum sliding stroke. At this time, the automobile rear seat 1 is slid to the front end, and the rear space of the automobile rear seat 1 can be conveniently accessed to mount the rear end mounting bolt. When the rear end mounting bolt is mounted, the second upper stop point 6 is arranged in the eighth through hole 238. The second lower stop point 7 can abut against the second upper stop point 6, that is, the automobile rear seat 1 has a second maximum sliding stroke. Since the second maximum sliding stroke is smaller than the first maximum sliding stroke, the original first maximum sliding stroke can be inhibited. That is, when the second lower stop point 7 abuts against the second upper stop point 6, there is still a distance between the first upper stop point 4 and the first lower stop point 5, that is, the first upper stop point 4 does not abut against the first lower stop point 5.

[0120] The other settings of the embodiment are the same as those of the third embodiment, and will not be described here.
