Description

Technical Field

[0001] The invention relates to the technical field of automobile seat structures, and in particular to an automobile second-row seat structure and method. Background Art

[0002] Currently, most SUV models are five-seater, that is, two groups of seats in the front row and three groups of seats in the back row. However, with the continuous development of automobiles, five-seater SUVs can no longer meet the needs of some families, and six-seater or seven-seater SUVs have come into being. Seven-seater SUVs have a larger riding space and can carry more passengers, providing convenience for many car owners. Among them, in six-seater or seven-seater SUV models, the second row of seats is generally arranged as two groups of separate seats, and a passage needs to be reserved between the second row left seat and the second row right seat for passengers to lead to the third row of seats. There are also some models that set the second row of seats as an integrated structure, but this arrangement requires passengers to fold down the second row of seats first when they want to sit in the third row, which is inconvenient to move. Therefore, multi-seat SUV models generally choose to arrange two groups of separate seats in the second row, and reserve a passage in the middle.

[0003] The inventor discovered that when a car needs to carry more people and more items, the three rows of seats need to be folded down to increase the loading space. On this basis, the second row of seats can only accommodate two people and cannot accommodate three people. Therefore, the current multi-seat SUV models cannot meet the riding needs of five people at the same time after the three rows of seats are folded down. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a second-row seat structure and method for an automobile, by which a stretchable seat body is moved to the second-row right seat through a sliding track inside the second-row left seat and the stretchable seat body is fixed by a locking mechanism; when the three-row seat is folded down, the second-row seat can accommodate three people instead of two people, thereby meeting specific needs.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0031] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0032] Embodiment 1

[0033] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 6 As shown, a second row seat structure for a car includes a second row left seat 1 and a second row right seat 20. The second row left seat is open on one side near the second row right seat, and a accommodating space for a stretch seat body 3 is provided inside. The stretch seat body 3 slides with the second row left seat 1, moves to the second row right seat through a sliding track, and is fixed by a locking mechanism 15. After the three rows of seats are folded down, the second row seats can be changed to accommodate three people.

[0034] like Figure 1 and Figure 2As shown, the accommodation space of the second row of left seats 1 is slidably matched with the stretch seat body 3 through a sliding track; the stretch seat body 3 in the accommodation space can be pulled out through the opening, and the sliding track includes an upper sliding track 8, a middle sliding track 5 and a front sliding track 6 which are transversely arranged on the seat frame at the accommodation space inside the second row of left seats 1, and are respectively used to slide with the sliders at the corresponding positions outside the stretch seat body 3. Among them, the upper sliding track 8 corresponds to the middle and upper position of the backrest of the second row of left seats, and is used to cooperate with the slider at the top of the back side of the stretch seat body 3. The middle sliding track 5 corresponds to the lower end position of the backrest of the second row of left seats 1, and is used to cooperate with the slider on the lower side of the rear end of the cushion of the stretch seat body 3. The front sliding track 6 corresponds to the front end of the cushion of the second row of left seats 1, and is used to cooperate with the slider on the lower side of the front end of the cushion of the stretch seat body 3. Through the setting of the sliding track, the stretch seat body 3 can be pulled out from the second row of left seats 1 from the opening side.

[0035] like Figure 1 As shown, a headrest retracting area 10 is provided on the backrest of the stretch seat body, and an emergency headrest 11 is provided at the headrest retracting area 10 through a telescopic mechanism. The telescopic mechanism is a foldable headrest fixing rod 12, and the emergency headrest 11 can be extended or retracted into the backrest through the foldable headrest fixing rod 12. The structural form of the foldable headrest fixing rod 12 can refer to the telescopic rod structure on an umbrella or a suitcase. When the emergency headrest 11 is retracted to the headrest retracting area 10 when the second row of left seats is retracted, the emergency headrest 11 needs to be retracted to the headrest retracting area 10, and the emergency headrest 11 can be pulled out after the stretch seat body 3 is pulled out.

[0036] The stretch seat body 3 includes a seat cushion, a backrest and a corresponding frame. The backrest and the seat cushion are rotated together on one side close to each other through a support shaft 9. The stretch seat body 3 itself cannot adjust the angle of the backrest and the seat cushion, and needs to be adjusted synchronously with the second row left seat 1.

[0037] like Figure 1 and Figure 2 As shown, a groove is provided at the top of the backrest of the stretch seat body 3 near the second row right seat 20, and a limiting mechanism 14 is provided at a corresponding position at the top of the second row left seat 1. The limiting mechanism 14 includes a limiting member 141 that can be pushed downward so that the bottom end of the limiting member 141 is inserted into the groove to limit the stretch seat body 3.

[0038] like Figure 6As shown, the main body of the limiting member 141 is a pin structure, and an annular baffle 142 is provided around the middle position. A spring 143 is sleeved around the limiting member 141 on the top of the annular baffle 142. The top of the spring 143 abuts against the internal frame of the second row of left seats 1. A through hole is correspondingly provided on the second row of left seats 1, so that the top of the limiting member 141 extends to the top of the second row of left seats. The bottom of the spring 143 abuts against the annular baffle 142, so that the limiting member 141 has a tendency to move downward. After the groove and the limiting member are aligned, the bottom of the limiting member can be inserted into the groove to limit the stretching seat body. Specifically, by pulling the limiting member 141 upward, the bottom of the limiting member leaves the groove, and the limit on the stretching seat body 3 is released at this time, and the stretching seat body 3 can be pulled out afterwards. When retracting the stretching seat body 3, the stretching seat body 3 is also pulled up. After the stretching seat body 3 is retracted, the limiting member 141 is lowered to achieve locking the stretching seat body 3 inside the second row of left seats 1.

[0039] like Figure 1 and Figure 5 As shown, the accommodating space is provided with multiple groups of annular grooves 101 on the side away from the second row of right seats, and an elastic pushing member 13 is provided inside the annular groove 101. The elastic pushing member 13 is a spring structure. The elastic pushing member 13 can be compressed when the stretching seat body is retracted to the second row of left seats. When the stretching seat body 3 is unlocked by the limiting mechanism 14, the stretching seat body 3 can be pushed to the right under the action of the elastic pushing member 13, so that the stretching seat body 3 pops out, which is convenient for the stretching seat body 3 to continue to be pulled to the right.

[0040] like Figure 1-Figure 4 As shown, a locking mechanism 15 capable of forming a locked state is provided on one side where the stretch seat body 3 and the second row right seat 20 are close to each other.

[0041] like Figure 1 As shown, the locking mechanism 15 includes a plurality of groups of fixed anchor points arranged on the right side of the stretching seat body 3. In this embodiment, there are three groups, namely an upper fixed anchor point 2, a middle fixed anchor point 4, and a front fixed anchor point 7. The positions of the fixed anchor points are arranged corresponding to the sliding tracks, wherein the upper fixed anchor point 2 is arranged at the top right side of the backrest of the stretching seat body 3, the middle fixed anchor point 4 is arranged at the rear end of the right side of the seat cushion, and the front fixed anchor point 7 is arranged at the front end of the right side of the seat cushion.

[0042] like Figure 1 As shown, the fixed anchor point is a plate-like structure, and a locking hole is provided on the fixed anchor point. The locking hole is a through hole and can be engaged with the limit card.

[0043] The left side of the second row right seat 20 corresponds to the opening, and the locking mechanism 15 also includes a locking rod group 16 arranged at the left side opening of the second row right seat 20. Figure 3 and Figure 4 shown.

[0044] The locking rod set 16 has an L-shaped cross-section, including a first locking rod 161 arranged along the backrest and a second locking rod 162 arranged along the seat cushion, and the first locking rod 161 and the second locking rod 162 are hinged near one end of each other. The first locking rod 161 and the second locking rod 162 are provided with corresponding limit cards at the positions corresponding to the fixed anchor points on the left side, and the limit cards on the locking rod set can cooperate with the locking holes for limit.

[0045] Specifically, the limit card includes an upper limit card 17, a middle limit card 18 and a front limit card 19. The limit card is a plate-like structure, and a pin is provided on one side of the plate-like structure for inserting into a locking hole on a fixed anchor point.

[0046] The bottom of the second locking rod 162 is supported by the seat frame, and a locking member 151 is provided at one end of the first locking rod 161 and the second locking rod 162 which are away from each other. Figure 4 As shown, the top end of the first locking rod 161 is fixedly connected to the locking piece 151 , and the bottom of the second locking rod 162 near the front end is fixedly connected to the locking piece 151 .

[0047] The structure of the locking piece 151 at the first locking rod 161 is similar to that of the limiting piece 141. The locking piece 151 is a pin structure. An annular blocking piece 152 is provided around the middle part of the locking piece 151. A spring 153 is sleeved around the locking piece above the annular blocking piece 152. One end of the spring 153 abuts against the annular blocking piece 152, and the other end is fixedly abutted against the internal frame of the second row right seat. The spring 153 has an elastic force that presses down the first locking rod 161, and the top end of the locking piece 151 extends out of the backrest.

[0048] The locking member 151 at the second locking rod 162 is different in structure from the locking member 151 at the first locking rod 161. The two differ by an annular baffle 152. The locking member 151 at the second locking rod 162 includes a pin shaft, and a spring 153 is sleeved on the outer side of the pin shaft. The top end of the spring is connected to the second locking rod 162, and the bottom end is connected to the internal frame of the second row right seat. Since the bottom of the second locking rod 162 is supported by the seat frame 201, the position of the seat frame 201 is coordinated to adjust the lowest height of the second locking rod 162, so that the spring on the locking member 151 at the second locking rod 162 is stretched, and the bottom end of the locking member 151 extends downward from the seat cushion. There is a channel inside the second row right seat for the locking rod group to move up and down, so that the locking rod group can move up and down in a small range.

[0049] When the stretch seat body 3 is pulled to the right toward the second row right seat 20, the locking piece 151 at the first locking rod 161 is pulled up and the locking piece 151 at the second locking rod 162 is pushed up, so that the locking rod group moves upward, driving the limit card to move upward, and the fixed anchor point can be moved to the frame position of the second row right seat 20 and supported by the seat frame 201. After the fixed anchor point is aligned with the limit card, the locking piece 151 is released, and the pin shaft on the limit card is engaged with the locking hole on the fixed anchor point, so as to prevent the stretch seat body 3 from accidentally retracting along the sliding track to ensure safety.

[0050] It can be understood that the upper limit card 17, the middle limit card 18 and the front limit card 19 respectively correspond to the upper fixed anchor point 2, the middle fixed anchor point 4 and the front fixed anchor point 7.

[0051] This embodiment provides a slidable stretchable seat body on the second row left seat in a six-seat or seven-seat SUV model, and provides a locking mechanism for the lockable stretchable seat body on the second row right seat, so as to achieve the effect and purpose of allowing three people to sit in the second row of seats after the three rows of seats are folded down, thereby realizing the effect of the emergency riding mode.

[0052] Embodiment 2

[0053] In a typical embodiment of the present invention, reference is made to Figure 1-Figure 6 As shown, a method for using a second-row seat structure for an automobile, using the second-row seat structure for an automobile as described in Embodiment 1, comprises the following steps:

[0054] When the stretch seat body 3 is needed, the stretch seat body and the second row left seat are unlocked by the limiting mechanism 14, the elastic pushing member 13 pops out the stretch seat body, and the stretch seat body 3 is pulled to the right through the sliding track inside the second row left seat 1.

[0055] After pulling out the stretch seat body, adjust the angles of the second row left seat 1 and the second row right seat 20 so that the right side of the stretched seat body slides to the second row right seat 20 through the sliding track. The locking rod group drives the limit card to move up through the locking piece 151. After adjusting the relative position of the limit card and the fixed anchor point, release the locking piece so that the three groups of limit cards are correspondingly engaged with the three groups of fixed anchor points to prevent the stretch seat body from accidentally retracting. The right fixed anchor point of the stretch seat body is supported by the frame of the second row right seat, and the fixed anchor point is connected inwardly with the internal frame of the stretch seat body 3. The left side of the stretch seat body 3 is supported by the corresponding sliding track, so that the stretch seat body 3 has sufficient strength to ensure the safety of riding.

[0056] When it is necessary to retract the stretchable seat body 3, the three groups of fixed anchor points are unlocked through the locking piece 151, and the stretchable seat body 3 is pushed to the left. After the stretchable seat body 3 is completely retracted into the internal accommodating space of the second row of left seats, the limiting piece 141 is plugged into the groove to limit the stretchable seat body 3. At this time, the second row of seats returns to the double seat mode.

[0057] It is understandable that a safety belt structure can be provided on the backrest and the edge of the seat cushion of the stretchable seat body. The left and right of this embodiment are defined based on the direction from the rear of the vehicle to the front of the vehicle. When the direction from the front of the vehicle to the rear of the vehicle is defined as the reference, the structure of this embodiment should be changed symmetrically. Therefore, in the preferred example, any one of the two seats in the second row can be selected to accommodate the seat of the stretchable seat body, and the other seat needs to be provided with a corresponding locking mechanism.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
