Since the first side pillow 310 and the first side pillow 320 are mirror-symmetrical, the structure of the second side pillow will not be described in detail.

Example 2

Furthermore, the utility model discloses still provide the second embodiment, embodiment 2 only lies in the difference of first installation department 210 and/or second installation department 220 with embodiment 1's difference, and all the other structures are completely unanimous, consequently no longer describe the beneficial effect of all the other structures of embodiment 2 and corresponding production repeatedly.

Embodiment 2 referring to fig. 7 to 10, the first mounting portion 210 and/or the second mounting portion 220 includes: the opening towards the U type groove 231 of inserted bar 401, and with fastener 232 of U type groove 231 notch looks adaptation, U type groove 231 with fastener 232 cooperation makes first installation department and/or second installation department be fixed in on inserted bar 401.

Specifically, two opposite side walls of the U-shaped groove 231 are respectively provided with a sliding groove 2311, two ends of the fastener 232 corresponding to the sliding grooves are respectively provided with a sliding rail 2321, and the sliding grooves 2311 are adapted to the sliding rails 2321, so that the fastener 232 is fixed on the U-shaped groove 231. The technical characteristics can also realize that the installation and the disassembly of the first installation part or/and the second installation part are more convenient.

Further, a through groove 2321 is formed in the fastener 232, the through groove penetrates through the fastener 232, a shifting arm 234 is disposed in the through groove 2321, the shifting arm 234 is located on a surface far away from the U-shaped groove 231, the shifting arm 234 is hinged to a side wall of the through groove 2321, a butting block 233 is further disposed in the through groove 231, the butting block is located on a surface close to the U-shaped groove 231, and the butting block 233 is movably connected with the through groove 2321, so that the butting block 233 is completely accommodated in or exposed out of the through groove 2321. An end block 2340 is arranged at one end of the shifting arm 234 close to the abutting block 233, and the end block 2340 is rectangular, that is, the end block 2340 is provided with an end surface 2341 and a side surface 2342 adjacent to the end surface 2341. As shown in fig. 9, when the shift arm 234 is accommodated in the through groove 2321 during installation, the side 2342 abuts against the abutting block 233, at this time, the abutting block 233 is extruded by the side 2342 to expose the through groove 2321, and the part of the abutting block 233 exposed from the through groove 2321 extrudes the insert rod 401, so as to fix the car side headrest of the present invention on the insert rod 401; when the car side headrest needs to be detached, as shown in fig. 10, the toggle arm 234 is toggled to rotate to form a preset angle, such as 90 degrees, with the notch of the through slot 2321, at this time, the end surface 2341 corresponds to the abutting block 233, the abutting block 233 is no longer extruded by the toggle arm 234, so that the abutting block is completely accommodated in the through slot 2321, the abutting block 233 does not extrude the insert rod 401, and the car side headrest can be detached from the insert rod 401. This technical characteristic can strengthen the fastening of first installation department and/or second installation department for it is more firm to drive a vehicle in-process car side back cushion installation, uses more firmly safety.

Preferably, as shown in fig. 11, in order to enable the first mounting portion 210 and/or the second mounting portion 220 to be mounted to match with a plunger of an automobile of different models, the first mounting portion 210 and/or the second mounting portion 220 are fixed to the plunger more firmly, the first mounting portion 210 and/or the second mounting portion 220 are further provided with a plunger sleeve 236, and the plunger sleeve 236 is matched with the U-shaped groove 231; a clamping groove 2313 (please refer to fig. 8) is formed in the inner wall of the U-shaped groove 231, which is close to the port, a clamping protrusion 2361 is formed in a position of the plunger sleeve 236, which corresponds to the clamping groove 2313, and the plunger sleeve 236 is sleeved in the U-shaped groove through the matching of the clamping protrusion 2361 and the clamping groove 2313. The internal diameter of inserted bar cover 236 is less than the internal diameter in U type groove, during the actual use consequently, can dispose the inserted bar cover of different internal diameters for first installation department 210 and/or second installation department 220 can join in marriage the inserted bar 401 of adapting to different diameters, make the utility model discloses a car side back cushion convenient to use, it is nimble general.

Example 3

Furthermore, the present invention also provides a second embodiment, and embodiment 3 is different from embodiment 1 in the first mounting portion 210 and/or the second mounting portion 220. And the difference of the connecting rod 100, the rest structures are completely consistent, so the rest structures and the corresponding beneficial effects of embodiment 2 are not described again.

First, compared to the embodiment 1 in which the first and/or second mounting

portions

210 and 220 and the first and/or second side bolsters 310 and 320 are respectively disposed on the same side of the connecting rod 100, the first and/or second mounting

portions

210 and 220 and the first and/or second side bolsters 320 and 310 and 320 are respectively disposed on both sides of the connecting rod 100, in this embodiment, the first and/or second mounting

portions

210 and 220 and 310 and 320 are respectively disposed on both sides of the connecting rod 100, as shown in fig. 1 and 12, in particular, in the embodiment 1, the first and/or second mounting

portions

210 and 220 are mounted from the front of the car seat, the connecting rod 100 is mounted in front of the insert rod 401, and in the embodiment 3, the first and/or second mounting

portions

210 and 220 are mounted from the rear of the car seat, the connecting rod 100 is installed at the rear of the insertion rod 401.

Next, the connecting rod 100 of embodiment 3 is further provided with a bent portion with respect to the connecting rod 100 of embodiment 1; specifically, a first bending portion 112 is disposed at an end of the first connecting rod 110 close to the first side bolster 310, and a second bending portion 122 is disposed at an end of the second connecting rod 120 close to the second side bolster 320. Since the connecting rod 100 of this embodiment 3 is disposed behind the car seat, the head of the first side bolster 310 and the second side bolster 320 cannot completely rest on the first bolster 311 or the second bolster (not shown) after going backward relative to embodiment 1, and therefore, it is necessary to improve the connecting rod 100, and the first bending portion 112 and the second bending portion 122 are disposed to enable the positions of the first side bolster 310 and the second side bolster 320 to move forward relative to each other, so as to better fit the position of the head side rest, so that the structure of this embodiment is more reasonable, and the use is more comfortable.

The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
