Description

Technical Field

[0001] This utility model belongs to the technical field of automotive seat accessories, and relates to an automotive seat headrest. Background Technology

[0002] As people's living standards improve, their demands for the comfort of car seat headrests are also increasing. Headrests are an important component of car seat systems and occupant restraint systems, primarily used to support the driver's head and maintain a correct posture. In the event of a rear-end collision, headrests can effectively reduce the "whiplash effect" on the neck caused by inertia, thereby reducing the risk of neck injury. Neck pillows are an important part of headrests, mainly used to fill the gap between the neck and the seat, providing additional support, helping to maintain the natural curve of the cervical spine, reducing the burden on the cervical spine, and preventing neck pain and stiffness.

[0003] Currently, neck pillows on the market are divided into traditional wraparound neck pillows (i.e., the neck pillow is attached to the headrest rod of the headrest by elastic straps, such as a car seat leather that is easy to install disclosed in Chinese patent literature (application number: 202321734915.6)) and detachable neck pillows (i.e., the neck pillow is detachably connected to the headrest by several mounting rods, such as a multimedia car seat headrest and seat disclosed in Chinese patent literature (application number: 202510133063.2)). Traditional wraparound neck pillows cannot be stably fitted to the seat back and are prone to rotation and displacement during use, while the rigid connecting parts on detachable neck pillows are prone to causing pressure and discomfort. Therefore, neither traditional wraparound neck pillows nor detachable neck pillows can meet people's requirements for neck pillow comfort. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a car seat headrest. The technical problem this invention aims to solve is how to improve the comfort of using a car seat headrest.

[0005] The purpose of this utility model can be achieved through the following technical solution: A car seat headrest, wherein a headrest rod with several locking grooves is vertically arranged on the headrest seat, characterized in that a headrest foam and a neck support are arranged adjacently on the headrest seat, and an air bag, a neck support foam and a heating pad electrically connected to the car seat wiring harness are connected sequentially from back to front on the neck support, the air bag has an inflation / deflation port, the headrest seat is provided with a button and a locking piece that is engaged in the locking groove and locks the headrest rod, both the button and the locking piece are elongated, the locking piece is connected to the headrest seat by a second spring, the middle part of the button is hinged to the headrest seat, one end of the button protrudes from the headrest seat, and when the above end of the button is pressed, the other end of the button can push the locking piece to overcome the elastic force of the second spring and disengage from the locking groove of the headrest rod to unlock, the headrest seat is also provided with a first spring for the button to reset after being pressed.

[0006] This car seat headrest allows users to adjust the neck support height, fore-aft position, and temperature according to their needs. Specifically, to adjust the neck support height, the user presses a button to unlock the locking plate and headrest rod, then moves the headrest up and down to adjust the height. After adjustment, releasing the button causes the locking plate to re-engage with the headrest rod under the action of a second spring, locking the headrest rod and thus achieving the adjusted neck support height. To adjust the fore-aft position, an air pump connected to the airbag inflation / deflation port inflates the airbag, causing it to expand and move the airbag towards the fore-aft position. The neck support foam moves forward synchronously, or the air bag is deflated by an air pump. After the air bag deflates, it contracts and drives the neck support foam connected to it to move backward synchronously, thereby adjusting the front and back position of the neck support. When the temperature of the neck support needs to be adjusted, the user converts electrical energy into heat energy through the heating pad (heating element inside) which is electrically connected to the car seat wiring harness, so that the heating pad gradually heats up. After the power is turned off, the heating pad will gradually cool down, thereby adjusting the temperature of the neck support and providing the user with better neck support and comfort, effectively reducing neck fatigue and discomfort, and thus improving the comfort of using the car seat neck pillow.

[0007] In the aforementioned type of car seat headrest, the headrest base includes a base and a cover plate connected to the rear of the base. The headrest foam and neck support are both connected to the front of the base. A soft foam pad is embedded and fixed to the surface of the headrest foam. The neck support foam has a "U"-shaped cross-section and covers the neck support seat. The soft foam pad has a unique honeycomb-shaped independent closed-cell structure, providing strong cushioning performance. In the event of a vehicle collision, the headrest can quickly disperse the impact force, effectively reducing the risk of cervical spine injury and protecting the neck safety of the driver and passengers. The "U"-shaped cross-section of the neck support foam, covering the neck support seat, allows the neck support seat to guide and limit the forward and backward movement of the neck support foam, making the positional movement of the neck support foam more precise and stable.

[0008] In the aforementioned car seat headrest, the cover plate includes a first rear cover plate and a second rear cover plate connected sequentially from front to back to the base. The first rear cover plate has a clearance hole for the button to be exposed. The headrest rod is connected to the second rear cover plate. A mounting cavity is formed between the base and the second rear cover plate. A guide block is connected to the middle of the locking plate. The button, guide block, and lock are all disposed within the mounting cavity and move in a guided manner with the cavity wall. This facilitates the installation and removal of the car seat headrest. Simultaneously, the cavity wall of the mounting cavity can limit the movement of the button, guide block, and locking plate, making their positional movement more precise and stable.

[0009] In the aforementioned type of car seat headrest, the guide block has an outwardly protruding limiting portion and a spherical protrusion, the button has an arc-shaped surface that abuts against the spherical protrusion, and the cavity wall of the mounting cavity has an inwardly recessed receiving portion, with the limiting portion inserted into the receiving portion. This allows for more precise and stable movement of the guide block (including the locking plate), enabling the button to better push the locking plate out of the locking groove of the headrest rod and unlock after being pressed and oscillating.

[0010] In the aforementioned car seat headrest, the base has a hollow mounting post, the button has a mounting rod, the first spring is horizontally disposed within the mounting post, the mounting rod is inserted into the first spring, and both ends of the first spring are connected to the base and the button, respectively. The mounting rod simultaneously limits the movement of the button and the first spring, and the mounting post also limits the movement of the first spring, allowing the first spring to better drive the button to reset after being pressed.

[0011] In the aforementioned car seat headrest, there are two second springs, one horizontally and one vertically positioned at each end of the locking plate. The two ends of the second springs are connected to the locking plate and the second rear cover plate, respectively. This allows the second springs to better drive the locking plate to return to its original position after movement, resulting in more precise and stable movement of the locking plate.

[0012] Compared with existing technologies, the advantages of this car seat headrest are: the height, fore-aft position, and temperature of the neck support can be adjusted according to the user's needs, thereby providing better neck support and comfort, effectively reducing neck fatigue and discomfort, and thus improving the comfort of using the car seat neck pillow.

The middle of the button 8 is hinged on the headrest seat 1. One end of the button 8 protrudes from the headrest seat 1. When pressing the above-mentioned end of the button 8, the other end of the button 8 can push the locking piece 9 to overcome the elastic force of the second spring 11 and disengage from the locking groove 2a of the headrest rod 2 to form unlocking. The headrest seat 1 is further provided with a first spring 10 for resetting the button 8 after pressing.

[0022] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 , specifically, the headrest seat 1 includes a base 1a and a cover plate 1b connected to the rear of the base 1a. The headrest foam 3 and the neck support seat 4 are both connected to the front of the base 1a. A soft foam pad 12 is embedded and fixed on the surface of the headrest foam 3. The cross-section of the neck support foam 6 is in a "U" shape and covers the neck support seat 4.

[0023] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , more specifically, the cover plate 1b includes a first rear cover plate 1b1 and a second rear cover plate 1b2 that are sequentially connected to the base 1a from front to back. The first rear cover plate 1b1 has a让位孔1b11 for the button 8 to protrude. The headrest rod 2 is connected to the second rear cover plate 1b2. An installation cavity 13 is formed between the base 1a and the second rear cover plate 1b2. A guide block 14 is connected to the middle of the locking piece 9. The button 8, the guide block 14 and the locking piece 9 are all arranged in the installation cavity 13 and are in guiding cooperation with the cavity wall of the installation cavity 13 for front and back movement.

[0024] Referring to Figure 3 , Figure 5 and Figure 6 , further, the guide block 14 has a limiting portion 14a and a spherical convex portion 14b that protrude outwards respectively.
