Description

Technical Field

[0001] This disclosure relates to a seat frame for a vehicle that can be mounted in the interior space of the vehicle in a forward and backward movable manner, and that the seat frame can be used as a seat when unfolded and as a divider for separating luggage space when folded. Background Technology

[0002] The interior space of a vehicle can be mainly divided into a passenger seating area and a cargo space at the rear of the vehicle. Seats can be installed in the passenger seating area for passengers to sit, and a cargo space can be provided at the rear of the vehicle for loading items.

[0003] Traditionally, automobiles or SUVs feature a first row of seats including a driver's seat and a passenger seat, and a second row of seats including a passenger seat located behind the first row, with luggage space located behind the second row. In large SUVs or vans, a folding or unfolding third row of seats can be installed behind the second row. If the third row is unfolded, the space can be used as seating for passengers; if the third row is folded down, the space can be used as luggage space.

[0004] Traditional vehicles have limitations in expanding or shrinking luggage space or moving seat positions. Even when the second and third rows of seats are not in use, there are limitations in loading items because the expansion of luggage space is greatly restricted. Furthermore, even when the luggage space is not in use, there are limitations in expanding the space available for the second or third rows of seats. Additionally, separate partitions are required to separate passenger and luggage space.

[0005] Due to these limitations, the interior space of the vehicle cannot be used effectively. Summary of the Invention

[0006] This disclosure aims to solve the problems mentioned above and provides a vehicle seat frame that is movably connected to the interior space of the vehicle, such that the position of the seat frame can be changed and the seat frame can be freely unfolded or folded to be used as a seat or a partition to divide the interior space.

[0007] According to one aspect of this disclosure, a vehicle seat frame includes: a main frame, one end of which is connected to the vehicle to be movable forward and backward, and the other end of which is connected to a ring structure of the vehicle to allow the height of the main frame to be adjusted upward and downward; a sub-frame disposed inside the main frame and connected to the main frame to be rotatable relative to the main frame, thereby allowing the sub-frame to be unfolded and folded; and a guide rail in which the main frame is fitted, the guide rail providing a path along which the main frame is configured to move within the vehicle in a direction from the front side of the vehicle to the rear side of the vehicle or from the rear side of the vehicle to the front side of the vehicle.

[0008] The lower end of the main frame can be movably connected to the vehicle floor, and the upper end of the main frame can be connected to the vehicle's ring structure, so that the height of the main frame can be adjusted according to the height from the floor to the ring structure, and the guide rail is set on the vehicle floor.

[0009] A rack can be installed on the inner surface of the guide rail, and a pinion gear can be installed in the main frame assembled in the guide rail. The position of the main frame can be moved by the meshing relationship between the rack and the gear.

[0010] A drive mechanism with a drive gear can be installed in the main frame, so that the main frame moves along the guide rail as the drive mechanism rotates.

[0011] The subframe may include a seat back frame and a seat cushion frame, with the seat back frame connected side-by-side to the main frame, and the seat cushion frame rotatably connected to the seat back frame relative to the seat back frame, allowing the seat cushion frame to be unfolded and folded.

[0012] A headrest frame can be installed at the upper part of the seat back frame, and the headrest frame is connected to the seat back frame in a manner that allows it to move up and down.

[0013] The seat cushion frame can be located behind the seat back frame, so that the seat cushion frame is kept in a linear form when folded and has a curved shape when unfolded.

[0014] A motor can be installed on the inner surface of the seat back frame, and a protrusion can be embedded in the motor. When the seat back frame is unfolded, the protrusion extends toward the seat back frame, thereby adjusting the shape of the seat back frame.

[0015] The main frame may include a rigid material, and the subframe may include a flexible material that is more flexible than the rigid material.

[0016] An external cover may be installed on the subframe, and a winding reel may be provided at the lower end of the subframe. The external cover is wound around the winding reel, and as the subframe is unfolded or folded, the external cover may extend from or be wound into the winding reel. The external cover may include a mesh material.

[0017] The main frame may be equipped with a stopper, which is located at the connection point between the main frame and the sub-frame and fixes the sub-frame when it is deployed.

[0018] The subframe can be configured to rotate relative to the main frame by a predetermined angle, thereby being unfolded and folded.

[0019] The subframe can be configured to unfold so that it functions as a seat, and the subframe can be configured to fold so that it functions as a partition separating the interior space of the vehicle.

[0020] In the seat frame according to this disclosure, because the seat frame is movably connected to the vehicle floor and the ring structure and the height of the main frame can be changed according to the height of the ring structure, the passenger space or luggage space can be expanded or contracted according to the user's needs, thereby making efficient use of space.

[0021] Furthermore, since the subframe can be unfolded or folded to be used as a seat or partition, it can be used as a seat or partition depending on the situation.

[0022] Furthermore, because the subframe includes the seat back frame, seat cushion frame, and headrest frame, its shape and structure allow passengers to feel comfortable and provide a sense of stability. Attached Figure Description

However, it should be understood that embodiments based on the concept of this disclosure are not limited to the specifically disclosed embodiments, and this disclosure includes all modifications, equivalents, or alternatives falling within the spirit and scope of this disclosure.

[0031] When an element is referred to as "connected" or "accessed" to other elements, it should be understood that the element is not only directly connected or accessed to other elements, but also that there may be other elements between the element and the other elements. Conversely, when a component is referred to as "directly connected" or "directly accessed" to other components, it should be understood that there are no components between the component and the other components. Other expressions describing the relationship between structural elements, namely "located between" and "only located between" or "adjacent" and "directly adjacent," should be interpreted similarly as described above.

[0032] Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Like reference numerals denote like elements in the drawings.

[0033] This disclosure relates to a seat frame that is movable along the floor F of a vehicle. In this disclosure, the main frame 100 is movable, while the sub-frame 200 functions as a seat S when unfolded and as a partition when folded, thereby making free use of the vehicle's interior space. Specifically, in the case of three rows of seats, the seat frame can be used as a seat S as needed while dividing the space into luggage space and interior space, thereby making efficient use of the space.

[0034] Figure 1 This is a perspective view of a vehicle seat frame according to an embodiment of the present disclosure. (See reference) Figure 1 According to embodiments of the present disclosure, the seat frame of a vehicle may include a main frame 100, a sub-frame 200, and a guide rail 300.

[0035] The main frame 100 may have a ring shape. The lower end of the main frame 100 may be connected to the vehicle floor F, and the upper end of the main frame 100 may be connected to the vehicle's ring structure L.

[0036] The lower end of the main frame 100 can be movably connected to the floor F. A guide rail 300 can be mounted on the floor F, and the lower end of the main frame 100 is fitted into and connected to the guide rail 300, allowing it to move forward and backward along the guide rail 300. As the main frame 100 moves forward and backward along the guide rail 300 within the vehicle's interior space, the position of the seats or partitions can be adjusted. Figure 2 Guide rail 300 is shown.

[0037] The upper end of the main frame 100 can be connected to the ring structure L so that it can move along the ring structure L. Because the upper end of the main frame 100 is connected to the ring structure L, the height of the main frame 100 can be adjusted with the height of the ring structure L. Because the ring structure L of the vehicle has the following shape: the center of the vehicle body is the highest, and the height of the vehicle body decreases when moving forward and backward, the height of the ring structure L should vary according to the position of the main frame 100 inside the vehicle.

[0038] Therefore, the main frame 100 can be configured such that the upward / downward height of the main frame 100 is adjusted according to the height from the floor F to the ring structure L. For example... Figure 1 As shown, the height of the main frame 100 can be configured to change according to the movement of the main frame. In order to adjust the height of the main frame 100, the side surfaces of the main frame 100 can have a multi-stepped structure.

[0039] The subframe 200 can be disposed inside the main frame 100. The subframe 200 can be connected to the main frame 100 and can be rotated relative to the main frame 100 by a predetermined angle to be unfolded or folded. When unfolded, the subframe 200 defines approximately 90 degrees between itself and the main frame 100, thereby serving as a seat; when folded, the subframe is arranged side by side with the main frame 100, thereby serving as a partition separating the interior space of the vehicle body.

[0040] The vehicle's interior space can be divided into a luggage space for loading luggage and a passenger space for passengers. Because the subframe 200, when folded, acts as a divider to separate the vehicle's interior space, the luggage space and passenger space can be separated by changing the position of the subframe 200, thereby dividing the vehicle's interior space. Therefore, the vehicle's interior space can be freely divided for use.

[0041] When seating is required within the vehicle's interior space, the sub-frame 200 can be used as a seat by positioning the main frame 100 in a suitable location and unfolding the sub-frame 200. Furthermore, when the luggage space should be separated from the passenger space for luggage loading, the luggage space can be created by folding the sub-frame 200 and moving the main frame 100. In this way, the limited interior space of the vehicle can be used effectively.

[0042] Figure 2 and Figure 3 This is a view showing the appearance of a moving seat frame of a vehicle according to an embodiment of the present disclosure.

[0043] refer to Figure 2 and Figure 3 The guide rail 300 can be a path along which the main frame 100 moves forward and backward within the interior space of the vehicle. The guide rail 300 can be mounted on the floor F of the vehicle, and the lower end of the main frame 100 can be fitted into the guide rail 300.

[0044] refer to Figure 3 A rack 310 can be formed on the inner surface of the guide rail 300, and a gear 101 can be formed on the outer surface of the main frame 100 that is mounted in the guide rail 300. When the main frame 100 moves, the gear 101 can move along the rack 310. That is, the position of the main frame 100 is moved by the meshing relationship between the rack and the gear. In addition, the main frame 100 can simply slide on the guide rail 300. In this case, a magnetic module can be provided to fix the position of the main frame 100.

[0045] Furthermore, the main frame 100 may be equipped with a drive device 103 that drives the gear 101. This drive device 103 can be connected to the gear 101 via a shaft 102, and can drive the gear 101 so that the gear 101 moves along the rack 310 as the gear 101 rotates. The direction of movement of the main frame 100 can be controlled by adjusting the rotation direction of the drive device 103. The position of the main frame 100 can be adjusted by operating the drive device 103.

[0046] Figure 4 and Figure 5 This is a view showing the appearance of a vehicle seat frame unfolded or folded according to an embodiment of the present disclosure. Figure 4 It only shows Figure 3 The view of the main frame 100 and the sub-frame 200 in the middle.

[0047] refer to Figure 4 and Figure 5 According to embodiments of the present disclosure, the sub-frame 200 of a vehicle seat frame may include a seat back frame 210 and a seat cushion frame 230. The seat back frame 210 may be connected side-by-side to the main frame 100 to support a passenger, for example, when the passenger is seated. The seat cushion frame 230 may be rotatably connected to the seat back frame 210, such that the seat cushion frame 230 can be unfolded and folded. Figure 4 and Figure 5 As shown, the seat cushion frame 230 can be rotated to be positioned facing forward when it moves to the underside of the seat back frame 210, thereby forming a seat.

[0048] Furthermore, a headrest frame 220 can be provided at the upper part of the seat back frame 210, and this headrest frame is connected to the seat back frame 210 in a manner that allows it to move forward and downward. The headrest H corresponds to the part where the passenger's head is located when the passenger is seated. The headrest frame 220 can be inserted through the upper part of the seat back frame 210 when not in use, and can be lifted upward to extend to the upper side of the seat back frame 210 when in use. Since the headrest frame 220 can be inserted and extended, it can prevent the headrest frame 220 from unnecessarily occupying space, thereby making efficient use of space.

[0049] The main frame 100 can be connected to the vehicle frame and can be made of a rigid material such as metal to firmly support the sub-frame 200. Because the sub-frame 200 comes into contact with the passenger's body, the sub-frame can be made of a flexible material that is more flexible than a rigid material.

[0050] The seat cushion frame 230 can be inserted into the rear of the seat back frame 210 to be stored in a folded state, and in this folded state, the seat cushion frame can be kept in a straight shape by the seat back frame 210. When unfolded, the seat cushion frame can have a curved shape to allow the passenger to sit comfortably. The sub-frame 200 can be made of a flexible material so that the shape of the seat cushion frame 230 can deform according to their usage. Therefore, when the sub-frame 200 is used as a divider, the seat cushion frame 230 can be stored in a straight form to obtain luggage space, while when the sub-frame 200 is used as a seat, the seat cushion frame 230 can have a curved shape to make the passenger feel comfortable when seated.

[0051] In addition, the seat cushion frame 230 may include a first seat cushion frame 231 that supports the lower body of the seated passenger and a second seat cushion frame 232 that supports the arm. The second seat cushion frame 232 may be positioned at the height of the passenger's arm, and the center of the second seat cushion frame 232 may have an upwardly curved shape so as to support the passenger's arm.

[0052] refer to Figure 5 The main frame 100 may be provided with a stop 500 for fixing the sub-frame 200. The stop 500 can be inserted into the sub-frame 200 at the point where the sub-frame 200 connects to the main frame 100. If the stop 500 is inserted into the sub-frame 200 while it is rotated to its unfolded state, the sub-frame 200 can be fixed, preventing reverse rotation. Therefore, when a passenger is seated, the seat can be stably fixed by inserting the stop 500 into the sub-frame 200.

[0053] Figure 6 This is a cross-sectional view of a vehicle seat frame according to an embodiment of the present disclosure. Figure 5The subframe 200 is shown in its unfolded state.

[0054] refer to Figure 6 A motor 240 can be mounted on the inner surface of the seat back frame 210. Since the passenger rests their back against the seat back frame 210, the passenger feels comfortable when the seat back frame 210 has a shape similar to a back. A protrusion 250 protruding towards the seat back frame 210 is embedded in the motor 240, and the protrusion 250 can be extended when the motor 240 is driven. The protrusion 250 can push the seat back frame 210 outward, causing the shape of the seat back frame 210 to bend and deform.

[0055] The motor 240 can be configured to be driven by the movement of the seat cushion frame 230. When the seat cushion frame 230 rotates, the shape of the seat back frame 210 is curved due to the protrusion 250 extending from the motor 240, so that the seat back frame 210 can be transformed into a shape that feels comfortable when the passenger is seated.

[0056] Figure 7 This is a cross-sectional view of the mesh seat and spool 410 of a vehicle seat frame according to an embodiment of the present disclosure.

[0057] refer to Figure 7 An external cover 400 may be installed on the sub-frame 200. This external cover 400 may be made of a mesh material exhibiting excellent ventilation and drying efficiency. A reel 410 may be provided at the lower end of the sub-frame 200, on which the external cover 400 is wound.

[0058] The outer cover 400 can be wound onto the reel 410 for storage, and the outer cover can extend from or be wound into the reel 410 to the required extent depending on the folded or unfolded state of the sub-frame 200. If the sub-frame 200 is folded and then unfolded, the outer cover 400 extends from the reel 410 along the sub-frame 200 to cover the entire sub-frame 200.

[0059] As described above, the seat frame of the vehicle according to this disclosure can be movably installed in the interior space of the vehicle, and the space can be utilized because it can be expanded and contracted into passenger space or luggage space. When several passengers are riding, the main frame 100 can be moved to the rear of the vehicle to obtain a spacious passenger space. Furthermore, when loading a large amount of items, the main frame 100 can be moved to the front of the vehicle to obtain a spacious luggage space.

[0060] Specifically, the subframe 200 can be rotatably connected to the main frame 100 so that it can be folded or unfolded, and thus can be used as a seat or partition, and therefore, there is no need to provide seats and partitions separately.

[0061] Although this disclosure has been shown and described with reference to specific embodiments thereof, it will be apparent to those skilled in the art that various modifications and changes may be made to this disclosure without departing from the spirit and scope of the disclosure as defined by the claims.
