Description

Technical Field

[0001] This utility model relates to a cover for a movable headrest and a car seat. Background Technology

[0002] With the continuous development of automotive technology and the increasing demand for comfort from consumers, the functionality and convenience of modern car seats have been significantly improved. Many models on the market now feature fully reclining, double-bed-like seats in both the first and second rows, providing passengers with a more comfortable resting space. However, to achieve this double-bed-like configuration, the headrests need to be removed or folded down to prevent them from interfering with the seat's adjustment during folding.

[0003] To address the inconvenience of manually removing the headrest, an electrically powered, movable headrest mechanism was proposed. This mechanism automatically controls the folding motion of the headrest, greatly improving user convenience. However, during the electrically folding process, the extension position of the headrest rod within the seat back changes, causing the angle and position between the headrest rod and the seat back to shift during movement. This results in a significant aesthetic issue: the opening at the headrest rod exit point becomes exposed in different folded states, creating irregular openings that severely impact the seat's aesthetics and overall visual appeal.

[0053] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings. In this specification, the same or similar reference numerals denote the same or similar components. The following description of the embodiments of this utility model with reference to the accompanying drawings is intended to explain the overall inventive concept of this utility model and should not be construed as a limitation thereof.

[0054] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details.

[0055] Figure 1A diagram is shown of a car seat including a cover 10 according to an embodiment of the present invention. Figure 2 This shows the movable headrest 30 when it is changed to the fully folded state. Figure 1 A diagram of a car seat.

[0056] like Figure 1-2 As shown, the car seat may include a movable headrest 30 and a seat back 40. The movable headrest 30 is connected to the seat back 40 via a headrest rod 20. The movable headrest 30 provides head support for the passenger. As an example, the movable headrest 30 can be electrically folded to switch to a folded state, thereby facilitating the conversion of the car seat into a bed mode. However, embodiments of the present invention are not limited to this; for example, the movable headrest 30 may also be able to move back and forth relative to the seat back 40.

[0057] The seat back 40 provides back support for the passenger. The surface of the seat back 40 may have an outlet for a headrest rod 20, through which the headrest rod 20 extends out of the seat back 40. One end of the headrest rod 20 is fixed to a movable headrest 30, and the other end extends into the seat back 40 and connects to a folding mechanism within the seat back 40. Therefore, when the movable headrest 30 moves (e.g., folds), the headrest rod 20 correspondingly changes its angle and position relative to the seat back 40.

[0058] According to an embodiment of the present invention, the car seat also includes a cover 10. The cover 10 is mounted on the seat back 40, specifically at the exit position of the headrest rod 20 from the seat back 40. Figure 1-2 As shown, the headrest rod 20 can extend through the cover 10. According to an embodiment of the present invention, the cover 10 is configured to automatically adjust itself to follow the movement trajectory of the headrest rod 20 throughout the folding process, thereby always maintaining effective coverage of the exit position of the headrest rod 20. This ensures that the car seat maintains a good visual effect in various usage states, improving the user experience and the overall quality of the product.

[0059] Figure 3 A perspective view of the cover 10 according to an embodiment of the present invention is shown. Figure 4 A bottom side view of the cover 10 according to an embodiment of the present invention is shown. Figure 5 A bottom side view of the cover 10 according to an embodiment of the present invention is shown from another angle.

[0060] like Figure 3-5As shown, the cover 10 may include a base 100 and a first sliding cover 221 and a second sliding cover 222. The first sliding cover 221 and the second sliding cover 222 are mounted on opposite sides of the base 100. The base 100 is the fixed part of the cover 10. The cover 10 can be mounted on the seat back 40 via the base 100. As an example, Figure 4 As shown, the base 100 has a certain length in the longitudinal direction X, and the first sliding cover 221 and the second sliding cover 222 can be arranged on opposite sides of the base 100 along the longitudinal direction X of the cover 10.

[0061] According to embodiments of the present invention, such as Figure 1-3 As shown, the first sliding cover 221 and the second sliding cover 222 can cooperate with each other to form a headrest rod hole 210 to accommodate the headrest rod 20 of the movable headrest 30. That is, the headrest rod 20 can extend from the seat back 40 through the headrest rod hole 210 of the cover 10.

[0062] As an example, such as Figure 3 As shown, the first sliding cover 221 may be provided with a first contact portion 2215 that contacts the headrest rod 20, and the second sliding cover 222 may be provided with a second contact portion 2225 that contacts the headrest rod 20. In the design state (i.e., Figure 1 In the normal working state shown (or the unfolded state of the movable headrest 30), the first contact portion 2215 and the second contact portion 2225 can be closely fitted to the corresponding outer surface of the headrest rod 20, so that the first contact portion 2215 and the second contact portion 2225 together surround the headrest rod 20, thereby forming a closed and complete headrest rod hole 210.

[0063] The size and shape of the headrest rod hole 210 in the design state can match the cross-section of the headrest rod 20 to ensure that the headrest rod 20 can pass smoothly through the hole without creating excessive gaps. Figure 1-3 In the embodiments described, the headrest rod 20 is shown to have a circular cross-section, and therefore the headrest rod hole 210 in the designed state also has a corresponding circular shape. However, the embodiments of the present invention are not limited to this; for example, the headrest rod 20 may be configured to have a cross-section of other shapes, such as square, and the headrest rod hole 210 in the designed state may be configured to be square accordingly.

[0064] According to an embodiment of the present invention, the first sliding cover 221 and the second sliding cover 222 are configured to slide independently relative to the base 100 as the headrest rod 20 moves. As an example, the first sliding cover 221 and the second sliding cover 222 remain in close proximity (or adjacent) to the headrest rod 20 during sliding relative to the base 100. Specifically, when the headrest rod 20 is in different folded states, the first sliding cover 221 and the second sliding cover 222 slide accordingly on the base 100 based on the position and angle of the headrest rod 20, ensuring that the first contact portion 2215 and the second contact portion 2225 remain in close proximity to the headrest rod 20, thereby effectively shielding the outlet hole at the outlet position of the headrest rod 20.

[0065] In this way, by setting a first sliding cover 221 and a second sliding cover 222 that can slide independently of each other and in accordance with the movement of the headrest rod 20, the headrest rod hole 210 formed by the two sliding covers can always maintain the correct alignment with the headrest rod 20. This ensures that the cover 10 can always effectively cover the exit hole of the headrest rod 20, regardless of the folded state of the headrest rod 20. Therefore, the appearance quality during the folding process is improved, ensuring both convenient folding function for customers and a visually appealing effect.

[0066] Furthermore, the cover 10 according to the embodiments of this utility model is simple in structure, convenient to install, and can be manufactured and structurally adjusted separately, thus it can be easily applied to a variety of headrest scenarios.

[0067] In this context, "closely adjacent" can be understood as the first sliding cover 221 directly abutting against the headrest rod 20 or having a very small gap between them. For example, in the design state and the folded-over state, there is typically a very small gap to allow the headrest rod 20 to extend smoothly through the headrest rod hole 210. During the folding process, the first sliding cover 221 may abut against the headrest rod 20 to slide accordingly with the movement of the headrest rod 20, thereby ensuring that the shielding function is always provided. Similarly, the second sliding cover 222 has the same positional relationship with the headrest rod 20, that is, directly abutting against it or having a very small gap between them.

[0068] In some embodiments, such as Figure 4-5 As shown, the cover 10 also includes an elastic member 230. The elastic member 230 is configured to connect the first sliding cover 221 and the second sliding cover 222, so that the first sliding cover 221 and the second sliding cover 222 are brought closer together. As an example, the elastic member 230 may be configured to have an elastic force that pulls the first sliding cover 221 and the second sliding cover 222 toward each other. Thus, in Figure 1 The design status shown or Figure 2In the folded-up state shown, under the action of the elastic member 230, the first sliding cover 221 and the second sliding cover 222 can abut against each other to form a closed and complete headrest rod hole 210. During the folding process, the elastic characteristics of the elastic member 230 not only allow the first sliding cover 221 and the second sliding cover 222 to automatically adjust the distance between them according to the changes in the position and angle of the headrest rod 20, but also ensure that the first sliding cover 221 and the second sliding cover 222 always remain closely adjacent to the headrest rod 20, thereby effectively surrounding the headrest rod 20 and providing a constant shielding function.

[0069] Figure 6 A bottom side view of a first sliding cover 221 according to an embodiment of the present invention is shown. Figure 7 A bottom side view of a second sliding cover 222 according to an embodiment of the present invention is shown.

[0070] In some embodiments, such as Figure 4-7 As shown, the first sliding cover 221 includes a first fixing part 261, and the second sliding cover 222 includes a second fixing part 262. One end of the elastic member 230 can be connected to the first fixing part 261, and the other end can be connected to the second fixing part 262. This connection method allows an elastic connection to be established between the two sliding covers, thereby achieving the elastic force that brings them together as described above, so that the first sliding cover 221 and the second sliding cover 222 are close to each other, ensuring that they can fit tightly against the outer surface of the headrest rod 20.

[0071] As an example, such as Figure 4 , Figure 6-7 As shown, the first fixing part 261 can be configured as a cylindrical structure with a first hole 281, and the second fixing part 262 can be configured as a cylindrical structure with a second hole 282. The first fixing part 261 and the second fixing part 262 can be arranged so that when the two sliding covers are mounted on the base 100, they face each other in the longitudinal direction X. In this case, both ends of the elastic member 230 can be inserted into the first hole 281 and the second hole 282 respectively to fix the elastic member 230 to the first sliding cover 221 and the second sliding cover 222 respectively, thereby forming a stable elastic connection between the first sliding cover 221 and the second sliding cover 222. With this structural design, the installation and replacement of the elastic member 230 can be simplified, while also ensuring the stability and reliability of the elastic member 230 during long-term use.

[0072] However, it should be noted that the embodiments of this utility model are not limited thereto, and any form of fixing structure for the elastic member 230 can be used, as long as the elastic member 230 can be stably fixed to the first sliding cover 221 and the second sliding cover 222 respectively.

[0073] Figure 8 A perspective view of a base 100 according to an embodiment of the present invention is shown.

[0074] In some embodiments, such as Figure 8 As shown, the base 100 may include a shielding member 110. An elastic member 230 is accommodated in the shielding space formed by the shielding member 110.

[0075] like Figure 5 and Figure 8 As shown, the shielding member 110 and the corresponding two sidewalls of the base 100 can cooperate to form a groove structure, thereby creating a semi-enclosed shielding space. After the cover 10 is assembled, the elastic member 230 is placed in this shielding space and thus shielded by the shielding member 110. In this way, the elastic member 230 is effectively protected and hidden to prevent the user from directly seeing the elastic member 230 from the outside. This further ensures that the cover 10 maintains a neat and aesthetically pleasing appearance in various operating states, achieving good overall appearance quality.

[0076] In some embodiments, such as Figure 4 As shown, the first sliding cover 221 and the second sliding cover 222 are disposed on opposite sides of the base 100 along the longitudinal direction X of the cover 10. The elastic member 230 includes a first tension spring 251 and a second tension spring 252, which are arranged on both sides of the headrest rod hole 210 in the transverse direction Y of the cover 10. The longitudinal direction X is perpendicular to the transverse direction Y.

[0077] In this embodiment, such as Figure 4 , Figure 6 and Figure 7 As shown, the first sliding cover 221 may include two first fixing parts 261, and the second sliding cover 222 may include two second fixing parts 262. The two first fixing parts 261 may be spaced apart from each other by a predetermined distance d1 in the lateral direction Y, wherein the predetermined distance d1 is greater than the maximum lateral distance d2 of the headrest rod holes 210 in the lateral direction Y. The two second fixing parts 262 may have a similar structural design to the two first fixing parts 261. After the cover 10 is assembled, one of the two first fixing parts 261 and a corresponding one of the two second fixing parts 262 face each other, and the other of the two first fixing parts 261 and a corresponding other of the two second fixing parts 262 face each other, thereby forming two pairs of fixing parts. Thus, a first tension spring 251 and a second tension spring 252 can be respectively installed through these two pairs of fixing parts. By making the predetermined distance d1 greater than the maximum lateral distance d2 of the headrest rod hole 210, it can be ensured that the first tension spring 251 and the second tension spring 252 are located on both sides of the headrest rod hole 210, so as not to block the extension of the headrest rod 20 from the headrest rod hole 210.

[0078] In this way, by using this double tension spring arrangement, when the headrest rod 20 is inserted into the headrest rod hole 210, the first tension spring 251 and the second tension spring 252 can simultaneously apply elastic tension, so that the first sliding cover 221 and the second sliding cover 222 can evenly fit against the outer surface of the headrest rod 20. This not only improves the stability of the shielding effect but also enhances the structural strength and service life of the entire cover 10.

[0079] In some embodiments, the first sliding cover 221 and the second sliding cover 222 may have the same shape as each other, and the first tension spring 251 and the second tension spring 252 may have the same shape as each other. Figure 6-7 As shown, the first sliding cover 221 and the second sliding cover 222 can adopt the same structural design. In this way, only one mold needs to be developed during the manufacturing process to produce both sliding covers simultaneously, reducing mold development costs and manufacturing complexity. In addition, the identical component design can simplify the assembly process and improve production efficiency. On the other hand, the first tension spring 251 and the second tension spring 252 can be of uniform spring specifications obtained through unified procurement. This not only ensures the consistency of the elastic force on both sides to avoid imbalance problems in the sliding cover movement that may be caused by differences in spring parameters, but also simplifies spare parts management and maintenance operations.

[0080] In some embodiments, such as Figure 5 and Figure 8 As shown, the base 100 may include a sliding guide groove 120. The sliding guide groove 120 is arranged to connect with the first sliding cover 221 and the second sliding cover 222 respectively to guide the sliding direction of the first sliding cover 221 and the second sliding cover 222. The sliding guide groove 120 may be located on both sides of the base 100 in the lateral direction Y of the cover 10. That is, the base 100 may include two sliding guide grooves 120 located on opposite sides. Each sliding guide groove 120 may be designed as an elongated groove, and the length direction of the sliding guide groove 120 is parallel to the longitudinal direction X of the cover 10.

[0081] Further, the first sliding cover 221 may include a first sliding groove 271. The first sliding groove 271 may be located on both sides of the first sliding cover 221 in the lateral direction Y and is configured to cooperate with the sliding guide groove 120 to slide along the sliding guide groove 120. The second sliding cover 222 may include a second sliding groove 272. The second sliding groove 272 may be located on both sides of the second sliding cover 222 in the lateral direction Y and is configured to cooperate with the sliding guide groove 120 to be able to slide along the sliding guide groove 120.

[0082] like Figures 5-6As shown, the first sliding groove 271 and the sliding guide groove 120 located on the same side of the base 100 can be connected to each other by staggered insertion, and the first sliding groove 271 can slide relative to the sliding guide groove 120 while maintaining connection with it. Thus, the sliding direction of the first sliding groove 271 can be guided by the sliding guide groove 120. Similarly, the first sliding groove 271 and the sliding guide groove 120 located on the other side of the base 100, the second sliding cover 222 and the sliding guide groove 120 located on the same side of the base 100, and the second sliding cover 222 and the sliding guide groove 120 located on the other side of the base 100 can be connected and guided in the same manner.

[0083] The first sliding cover 221 and the second sliding cover 222 can share the sliding guide groove 120 on their respective sides. This allows the second sliding cover 222 to be pushed further in that direction when the first sliding cover 221 slides toward the direction where the second sliding cover 222 is located. That is, the first sliding cover 221 can occupy more of the sliding guide groove 120, while the second sliding cover 222 occupies less of the sliding guide groove 120. Thus, the first sliding cover 221 and the second sliding cover 222 can achieve overall sliding movement relative to the base 100. At the same time, this will also cause a change in the position of the headrest rod hole 210 relative to the base 100.

[0084] In this way, by setting the sliding guide groove 120 and the first sliding groove 271 and the second sliding groove 272, the first sliding cover 221 and the second sliding cover 222 can perform the desired linear sliding movement on the base 100. Thus, when the headrest rod 20 is in different folded states, the two sliding covers can slide accordingly along the sliding guide groove 120 through their respective sliding grooves, so that the headrest rod hole 210 can always maintain the correct alignment with the headrest rod 20 to cooperate with the folding movement of the headrest rod 20.

[0085] In some embodiments, such as Figure 8 As shown, the base 100 may include a seat fixing part 130. The cover 10 is mounted to the seat back 40 via the seat fixing part 130. A headrest rod 20 extends from the seat back 40 through a headrest rod hole 210 in the cover 10. The seat fixing part 130 may be a structure capable of forming a reliable fixed connection with a corresponding structure of the seat back 40. As an example, the seat fixing part 130 may employ a snap-fit ​​connection, a screw connection, or other suitable mechanical connection method, as long as it ensures that the cover 10 is securely mounted on the seat back 40.

[0086] Reference Figure 9-11 Describe the sliding position and working state of the first sliding cover 221 and the second sliding cover 222 in different folding states. Figure 9The headrest bar 20 and cover 10 in design state A according to an embodiment of the present invention are shown. Figure 10 The headrest bar 20 and cover 10 in the folding process state B according to an embodiment of the present invention are shown. Figure 11 The headrest bar 20 and cover 10 in the folded-up state C according to an embodiment of the present invention are shown.

[0087] like Figure 8 and Figure 9 As shown, when the movable headrest 30 is in design state A (i.e., as shown) Figure 1 In the normal use state shown, the headrest rod 20 extends substantially vertically from the seat back 40, and its passage through the base 100 can be located at the first end E1 of the base 100. In this state, the headrest rod 20 can push the second sliding cover 222 to the corresponding end. At the same time, the first sliding cover 221 moves closer to the second sliding cover 222 under the action of the elastic member 230, so that the two are in abutting state to form a closed and complete headrest rod hole 210 to tightly surround the outer surface of the headrest rod 20. Thus, the headrest rod hole 210 can be correctly aligned with the headrest rod 20, that is, also located at the corresponding first end E1 of the base 100, thereby effectively concealing the outlet hole of the headrest rod 20.

[0088] like Figure 10 As shown, when the movable headrest 30 is in folding state B, the headrest rod 20 begins to rotate from a vertical position to an inclined position. Due to the tilt angle of the headrest rod 20, the projected length of its contact section with the cover 10 in the longitudinal direction X increases. In this situation, the second sliding cover 222 is continuously pushed towards end A and remains stationary, but the first sliding cover 221 is pushed in the opposite direction by the tilted headrest rod 20, thus sliding away from the second sliding cover 222. During this process, the elastic member 230 can apply an elastic tension to maintain a centripetal tension on both sliding covers, thereby ensuring that the first sliding cover 221 and the second sliding cover 222 can continuously and tightly surround the outer surface of the headrest rod 20 to maintain an effective shielding effect. In folding state B, the first sliding cover 221 and the second sliding cover 222 are no longer in contact, so the headrest rod hole 210 is not closed and complete to accommodate the tilted headrest rod 20 in folding state B.

[0089] like Figure 8 and Figure 11 As shown, when the movable headrest 30 is in the fully folded state C (i.e., as shown) Figure 2In the state shown, the headrest rod 20 moves from the first end E1 to the second end E2 of the base 100, thus pushing the first sliding cover 221 to the corresponding end. Simultaneously, the second sliding cover 222 moves closer to the first sliding cover 221 under the action of the elastic member 230. Figure 11 As shown, in this state, the headrest rod 20 is approximately vertical at the level of the headrest rod hole 210. Therefore, the first sliding cover 221 and the second sliding cover 222 can be restored to their abutting state to form a closed and complete headrest rod hole 210 that tightly surrounds the outer surface of the headrest rod 20. Thus, the headrest rod hole 210 can be correctly aligned with the headrest rod 20, that is, it is also located at the corresponding second end E2 of the base 100, thereby effectively concealing the outlet hole of the headrest rod 20.

[0090] During the process of returning from the completed folding state C to the design state A, the movement of the first sliding cover 221 and the second sliding cover 222 is exactly opposite. Under the elastic force of the elastic member 230, the first sliding cover 221 gradually moves closer to the second sliding cover 222, and the position of the headrest rod hole 210 also moves from the second end E2 of the base 100 to the first end E1 accordingly, so as to always maintain the correct alignment with the headrest rod 20.

[0091] Through this sliding adjustment mechanism, the cover 10 can continuously provide effective shielding during the entire folding process of the headrest 30, so that the outlet hole of the headrest rod 20 will not be exposed under any condition, thereby significantly improving the appearance quality and user experience of the seat.

[0092] It should be noted that, in this document, the movable headrest 30 is described as an example of the headrest rod 20 folding. However, the embodiments of the present invention are not limited to this; the movable headrest 30 may also be in the form of the headrest rod 20 moving back and forth relative to the seat back 40. Moreover, the cover 10 according to the embodiments of the present invention is also applicable to this type of movable headrest 30.

[0093] Although the present invention has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of the present invention and should not be construed as a limitation thereof.

[0094] While some embodiments of the present invention have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
