Description

Technical Field

[0001] This utility model relates to the field of massage equipment technology, and in particular to a manually adjustable sofa headrest cushion. Background Technology

[0002] Existing sofas with massage functions typically include a back frame and a back cushion located at the front of the back frame. The back frame contains a built-in massage mechanism, while the back cushion usually consists of an upper cushion and a lower cushion. The back cushion is usually quite thick, providing support for the user's head, shoulders, neck, and back when seated, offering good comfort. However, the massage mechanism's effectiveness is affected when massaging the user's shoulders and neck because of the upper cushion. To improve the massage effect on the user's shoulders and neck, the upper cushion can be detached and fixed, allowing it to be removed from the back frame when a massage is needed. While this improves the massage effect on the shoulders and neck, it also deprives the user's head of reliable support, affecting the user experience. Furthermore, the upper cushion needs to be stored away after removal, taking up space around the sofa and making it inconvenient to use. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides a manually adjustable sofa headrest cushion. The position of the upper cushion can be adjusted manually, which can provide both head support and neck and shoulder massage effects, and has better adaptability to users of different heights.

[0004] This utility model discloses a manually adjustable sofa headrest cushion, comprising a back frame, an upper backrest cushion and a lower backrest cushion disposed at the front of the back frame, and a massage mechanism capable of moving up and down disposed on the inner side of the back frame. Sliding strip seats are symmetrically disposed on both sides of the front of the back frame, and sliding strips are correspondingly disposed on both sides of the rear of the upper backrest cushion, which slide in a guide-sliding engagement with the two sliding strip seats. The upper backrest cushion can move up and down along the back frame through the guide-sliding engagement of the sliding strip seats and sliding strips. By placing the sliding strip seats and sliding strips on both sides of the front of the back frame, the upper backrest cushion is less prone to deformation and wrinkles when moving up and down, and the sliding strip seats and sliding strips are also kept away from the massage area of ​​the massage mechanism, so as not to affect the massage effect.

[0005] When a user needs to massage the neck and shoulders, they can manually push the upper backrest upwards to move it away from behind the neck and shoulders, which can improve the massage effect of the massage mechanism on the neck and shoulders. Users can adjust the upper backrest to a suitable position according to their head position to improve the support effect on the head. It can be adapted to users of different heights.

[0006] Furthermore, the upper end of the sliding strip extends along the contour of the front and upper surfaces of the back frame. Since the upper back cushion is soft, this design allows the upper back cushion to slide along the contour of the upper end of the back frame, which can reduce the space occupied above the sofa and is more aesthetically pleasing.

[0007] Furthermore, the lower back cushion is provided with sliding strips on both sides of its rear portion, which are guided and slidably engaged with the two sliding strip seats. This allows the lower back cushion to move up and down along the back frame through the cooperation of its sliding strips and sliding strip seats, and the user can adjust the position of the lower back cushion according to their needs.

[0008] Furthermore, the lower end of the upper cushion and the upper end of the lower cushion are detachably connected by buckles, zippers or Velcro, which allows the lower cushion to move upward synchronously when the upper cushion moves upward during operation.

[0009] Furthermore, the sliding bar seat includes a sliding groove and a slot arranged along its length direction. The sliding bar includes a sliding part that slides in the sliding groove and a supporting part that slides at the slot. The width of the slot is smaller than the width of the sliding part, which can prevent the sliding bar from coming off the sliding bar seat.

[0010] It should be noted that in this utility model, after the upper backrest and / or lower backrest are adjusted up and down, they can be held in that position by the pressure of the user leaning back. Alternatively, the position can be positioned after adjustment by setting a damping structure between the sliding bar and the sliding bar seat or between the backrest and the back frame. For example, the width of the sliding part can be designed to be slightly smaller than the width of the sliding groove, or a material with greater friction can be used at the contact position between the backrest and the back frame.

[0011] Furthermore, the upper part of the upper cushion is connected to a flexible fabric. The flexible fabric and the upper or rear part of the back frame are connected by buckles, zippers or Velcro to form a detachable connection. The flexible fabric can be used to connect with the upper cushion to prevent the upper cushion from falling off, and can also cover the gap between the upper cushion and the back frame to improve the aesthetics of the product.

Detailed Implementation

[0013] An embodiment of this utility model of a manually adjustable sofa headrest cushion is shown below. Figure 1-5 As shown: It includes a back frame 1, an upper back cushion 21 and a lower back cushion 22 located at the front of the back frame 1. The inner side of the back frame 1 is equipped with a massage mechanism that can move up and down. The inner structure of the back frame 1 is similar to that of a traditional massage chair, including a guide rail for the massage mechanism to move up and down. The front of the back frame 1 is blocked by a wear-resistant cloth. The two sides of the front of the back frame 1 are symmetrically provided with sliding strip seats 31 as shown in Figure 5. The two sides of the rear of the upper back cushion 21 are correspondingly provided with sliding strips 32 that slide and guide with the two sliding strip seats 31. The upper back cushion 21 can move up and down along the back frame 1 through the guiding sliding cooperation of the sliding strip seats 31 and the sliding strips 32. By positioning the sliding strip seats 31 and the sliding strips 32 on the two sides of the front of the back frame 1, the upper back cushion 21 is not easily deformed or wrinkled when moving up and down, and the sliding strip seats 31 and the sliding strips 32 are also kept away from the massage area of ​​the massage mechanism, so as not to affect the massage effect.

[0014] When a user needs to massage the neck and shoulders, they can manually push the upper backrest 21 upwards, so that the upper backrest 21 moves upwards from behind the neck and shoulders. Since there is no obstruction from the upper backrest 21, the massage effect of the massage mechanism on the neck and shoulders can be improved. The user can adjust the upper backrest 21 to a suitable position according to the position of their head, so as to improve the support effect on the head and adapt to users of different heights.

[0015] The upper end of the sliding strip seat 31 extends along the front and upper surface contour of the back frame 1, that is, the upper end of the sliding strip seat 31 has an arc-shaped section. Since the upper back cushion 21 is soft, it can deform appropriately. This design allows the upper back cushion 21 to slide along the upper contour of the back frame 1, which can reduce the space occupied above the sofa and is more aesthetically pleasing.

[0016] like Figure 4 , 5 As shown, the sliding bar seat 31 includes a sliding groove 311 and a slot 312 arranged along its length direction. The sliding bar 32 includes a sliding part 321 that slides in the sliding groove 311 and a support part 322 that slides at the slot 312. The width of the slot 312 is smaller than the width of the sliding part 321, which can prevent the sliding bar 32 from falling off the sliding bar seat 31.

[0017] Furthermore, in this embodiment, the upper ends of the sliding groove 311 and the slot 312 of the sliding strip seat 31 are both designed to be open, so that the upper backrest 21 can be removed from the back frame 1 as needed.

[0018] The upper part of the upper cushion 21 is connected to a flexible fabric 211. The flexible fabric 211 and the upper or rear part of the back frame 1 are connected by a buckle, zipper or Velcro to form a detachable connection. The flexible fabric 211 can be used to connect with the upper cushion 21 to prevent the upper cushion 21 from falling off. For example, the upper cushion 21 can be hung behind the back frame 1 after being removed. It can also cover the gap between the upper cushion 21 and the back frame 1 to improve the aesthetics of the product.

[0019] In addition, when no curved section is provided on the sliding strip seat 31, the upper end of the upper backrest 21 can be driven to move backward and downward by the traction of the flexible cloth 211, which can also limit its height and reduce the space occupied above the sofa.

[0020] In this embodiment, as Figure 4 As shown, multiple sliding strips 32 are arranged longitudinally on both sides of the upper backrest 21. This design can improve the deformation effect of the upper backrest 2, so that it can better adapt to the upper contour of the back frame 1.

[0021] In another embodiment, such as Figure 5 As shown, furthermore, the rear sides of the lower cushion 22 are respectively provided with sliding strips 32 that slide and guide with the two sliding strip seats 31, that is, the sliding strips 32 at the rear of the upper cushion 21 and the lower cushion 22 are both connected to the same sliding strip seat 31. This allows the lower backrest 22 to move up and down along the back frame 1 through the cooperation of its sliding bar 32 and sliding bar seat 31, and the user can adjust the position of the lower backrest 22 according to their needs.

[0022] The lower end of the upper cushion 21 and the upper end of the lower cushion 22 are detachably connected by buckles, zippers or Velcro, which allows the lower cushion 22 to move upward synchronously when the upper cushion 21 moves upward. This also allows the present invention to be adapted to more application scenarios. For example, when you want to massage the waist or other parts, you can move the lower cushion 22 upward synchronously.

[0023] After the upper backrest 21 and lower backrest 22 are adjusted up and down, they can be held in place by the pressure of the user leaning back. Alternatively, the position can be achieved by setting a damping structure between the sliding bar 32 and the sliding bar seat 31 or between the backrest and the back frame 1. For example, the width of the sliding part 321 can be designed to be slightly smaller than the width of the sliding groove 311, or a material with greater friction can be used at the contact point between the backrest and the back frame.

[0024] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
