Problems solved by technology

In order to ensure the balance of the rotation of the left and right sides of the backrest shoulder frame, it is also necessary to install a rotating transmission shaft between the left and right sides. However, there is a problem of collision safety when using the traditional recliner transmission shaft
Specifically, when the seat back is impacted from the rear, the passenger's body moves backwards and collides with the drive shaft, which may cause trauma to the relatively fragile neck and shoulders of the human body.

Embodiment 1

[0031] Such as figure 1 As shown, a recliner-type seat back shoulder adjustment structure includes two backrest fixed side panels 2 facing oppositely, and the upper parts of the two backrest fixed side panels 2 are respectively connected with backrest rotating side panels 1, The backrest rotating sideboard 1 is hinged to the corresponding backrest fixed sideboard 2, and also includes two recliners 3, and the two recliners 3 are respectively connected to the same side of the backrest rotating sideboard 1 and the backrest fixed sideboard. Side plate 2, wherein the backrest rotates side plate 1 to form the upper connecting plate of the recliner, the backrest fixed side plate 2 forms the lower connecting plate of the recliner, and a synchronously rotating transmission shaft is connected between the central shafts of the two recliners 3 4. An upper crossbeam 5 is connected between the upper parts of the two backrest rotating side plates 1, and a baffle plate 6 is arranged behind t...

Embodiment 2

[0035] The difference from Example 1 is that, as image 3 As shown, the end of the assembling section 4a protrudes toward the destroying section 4b and is provided with a connector 4c, and the connecting head 4c extends into the inner cavity of the destroying section 4b, and the two ends of the destroying section 4b are respectively sheathed in On the corresponding connecting head 4c, the barrel wall of the breaking section 4b is pressed against the corresponding connecting head 4c. This not only facilitates forming, but also makes the assembly section 4a and the breaking section 4b relatively fixed, transmit rotation, and fall off each other under a certain bending force.

Embodiment 3

[0037] The difference from Embodiment 1 is that the broken section 4b is a plastic rod whose flexural strength is lower than that of the assembled section 4a, and fracture failure also occurs during collision.

Abstract

An angle adjuster type seat back shoulder adjusting structure includes two backrest retaining side panels positioned facing each other, An upper part of that two backrest fix side plates is respectively connected with a backrest rotate side plate, the backrest rotating side plate is hinged with the corresponding backrest fixing side plate, At least one angle adjuster is connected with the backrestrotation side plate and the backrest fixing side plate on either side, and a synchronous rotation transmission shaft is connected with the backrest rotation side plate on the opposite side between the center shaft of the angle adjuster and the synchronous rotation transmission shaft, and the synchronous rotation transmission shaft comprises an assembly section and a failure section arranged alongthe same axial direction. The invention has the advantages that, When the angle adjuster is unlocked, the rotating side plates of the backrest on both sides can realize synchronous rotation under thecoordination of synchronous rotation transmission shafts, and the left and right sides can balance each other. When the synchronous rotation transmission shafts are subjected to a certain bending force, damage can occur to avoid damage to passengers, thus realizing shoulder adjustment and meeting the seat safety requirements.

Description

technical field [0001] The invention relates to a rotating transmission part, in particular to a recliner type seat back shoulder adjustment structure. Background technique [0002] The car seat back design emphasizes support for the shoulders and lumbar. In order to improve comfort, in addition to the adjustable angle of the seat back, some seats also increase the angle adjustment function of the neck and shoulders of the seat back to meet the comfort requirements of passengers of different postures and shapes. Similar to the adjustment of the overall angle of the backrest, the angle adjustment of the neck and shoulders of the backrest is generally realized by a recliner, that is, the rotation between the backrest shoulder frame relative to the backrest frame is realized through the recliner installed on the side tube (board) of the backrest . In order to ensure the balance of the rotation of the left and right sides of the backrest shoulder frame, it is also necessary to...
