Second carrier frame plate 24 is fixedly attached to the chair back 14 by multiple holes 50.
Recliner core members 26 can be installed to the first carrier frame plate 22 and the second carrier frame plate 24, and may operate in permission
It the unlocked state of relative rotation between the chair back 14 and seat bottom 12 and prevents opposite between the chair back 14 and seat bottom 12
The lock state of rotation.Recliner core members 26 can be for example round recliner core members or any other suitable class
The recliner core members of type.As shown in Figures 2 and 3, recliner core members 26 may include the first plate 54, the second plate 56 and locking machine
Structure 57.
First plate 54 can be fixed in a rotational direction relative to seat bottom 12 and can be attached to sealing ring 28.The
One plate 54 may include plate surface 84 and edge 86.Plate surface 84 may include hole 58, multiple triangle boss 59 and have peace
Fill multiple installation components 60 of end 62.Hole 58 can extend through the central part of plate surface 84.Multiple boss 59 can be with diameter
It is arranged to ground around hole 58, and can extends from plate surface 84, to limits recess portion.Each recess portion can be set multiple convex
Between two boss 59 in platform 59.
Multiple installation components 60 can extend from plate surface 84 along the contrary direction with boss 59.Installation component 60
It can extend from plate surface 84, so that each mounting end 62 is configured for mount to the corresponding recessed of the first carrier frame plate 22 (Fig. 5)
In slot 48.As shown in Figure 6 to 8, gap 89 can be limited between plate surface 84 and the second part 32 of the first carrier frame plate 22.
Edge 86 can in 360 degree extend around the periphery of plate surface 84 and can be attached sealing ring 28.
Second plate 56 can be fixed to the chair back 14 in a rotational direction, and can be generally circular flat disk object.
Second plate 56 may include plate surface 88 and edge 90.Plate surface 88 may include extending through the hole 85 of the center portion thereof point and from plate table
Multiple protrusions 92 that face 88 extends along the contrary direction with edge 90.Once recliner core members 26 are installed to second
On carrier frame plate 24, multiple raised 92 be may be housed in the corresponding recesses 94 of the second carrier frame plate 24.
The plate surface 88 of second carrier frame plate 24 and the second plate 56 can be attached by following laser welding modes, that is, be made
Obtain a part that laser beam contacts a part of the second carrier frame plate 24 and the plate surface 88 of the second plate 56.In this way, coming from the second support
The plate surface 88 of the material of frame plate 24 and the material of the plate surface 88 from the second plate 56 in the second carrier frame plate 24 and the second plate 56
Between contact area in melt, to form weld seam 93 between them, which reduce by the second carrier frame plate 24 and the second plate 56
The heat for linking together required and time.The second carrier frame plate 24 and the second plate 56 are linked together in the manner
Also increase the torsional strenght between the second carrier frame plate 24 and the second plate 56.In the manner by the second carrier frame plate 24 with
Second plate 56 links together and also peripheral part is made to be exposed to heat relatively fewerly, this by avoid making peripheral part be subjected to
The relevant distortion of heat and stress and increase the durability of recliner mechanism 18.Edge 90 can around plate surface 88 periphery with
360 degree of extensions, and may include the inside diameter surface (Fig. 3) with tooth 96.
Locking mechanism 57 may include multiple ratchets 98, cam 100, connector plate 102 and multiple helical springs 104.It is multiple
Pawl 98 can be disposed radially around the centre bore 58 of the first plate 54 and can be slidably mounted in the corresponding of the first plate 54
In recess portion.The edge of each pawl 98 may include the tooth 108 suitable for being engaged in a manner of engaging with the tooth 96 of the second plate 56.Often
A pawl 98 can also include the latch 110 positioned at the opposite end of tooth 108.
Cam 100 can be with hole 112 and multiple radial latch tabs 114 for arranging around hole 112 it is substantially round
The disk of shape.Cam 100 can be rotated relative to pawl 98 and the second plate 56, so that 114 property of can choose of latch tab
The latch 110 of pawl 98 is engaged, to move the engagement (that is, into unlocked state) of pawl 98 disengaging and the tooth 96 of the second plate 56.
Connector plate 102 is engaged with cam 100 and hub 27.Connector plate 102 may include disc portion 116 and from disc portion
116 vertically extending extensions 118.Disc portion 116 can have multiple flanges 120 extending therefrom.Each flange 120 with it is described
A corresponding helical spring 104 engagement in helical spring 104.Because each flange 120 is engaged with corresponding spring 104,
So connector plate 102 is so that latch tab 114 forces pawl 98 to be radially outwardly into the mode of lock state rotatably
Eccentric cam 100, thus the tooth 108 of pawl 98 is engaged with the tooth 96 of the second plate 56.
The extension 118 of connector plate 102 is engaged with hub 27 and cam 100, so that the rotation of hub 27 is (by the rotation of handle 20
Quote) cause the pawl 98 that is rotated to move of cam 100 to enter radially into and be detached from and the engagement of the tooth 96 of the second plate 56.
Hub 27 may extend through the length of recliner core members 26, and may include first end 122 and second end
Portion 124.First end 122 can engage handle 20, so that hub 27 and handle 20 are fixed to one another in a rotational direction.Hub 27 can wrap
Include the rectangular opening 126 for receiving cross member (not shown).The cross-sectional shape in hole 126 corresponds roughly to a part of cross member
Cross-sectional shape so that cross member and hub 27 to be fixed relative to each other in a rotational direction.
Referring to Fig. 2 to Fig. 8, sealing ring 28 is arranged between the first carrier frame plate 22 and the second carrier frame plate 24, and in its periphery
Recliner core members 26 are covered, to prevent clast and fluid damage component.Sealing ring 28 may include ontology 74, the first flange 76
With the second flange 78.First flange 76 can extend radially outwardly from the axial end portion of ontology 74, and can also at least partly enclose
Extend (for example, between 180 degree and 360 degree) around ontology 74.
The edge 86 of ontology 74 and the first plate 54 can be attached by following laser welding modes, that is, so that laser beam
Contact a part of a part of ontology 74 and the edge 86 of the first plate 54.In this way, material from ontology 74 and come
It is melted in the contact area between ontology 74 and the edge 86 of the first plate 54 from the material at the edge 86 of the first plate 54, at it
Between formed weld seam 95, which reduce the heat for linking together required by sealing ring 28 and the first plate 54 and times.As above
The torsional strenght also increased between sealing ring 28 and the first plate 54 that sealing ring 28 and the first plate 54 are linked together.
Sealing ring 28 and the first plate 54 are linked together as described above also make peripheral part relatively fewer be exposed to heat, this is logical
It crosses and avoids making peripheral part from being subjected to distortion relevant to heat and stress and increase the durability of recliner mechanism 18.
The second part 32 of first flange 76 and the first carrier frame plate 22 can be attached by following laser welding modes,
That is, making a part of a part of laser beam the first flange 76 of contact and the second part 32 of the first carrier frame plate 22.With this
The material of mode, the material from the first flange 76 and the second part 32 from the first carrier frame plate 22 is in the first flange 76 and
To form weld seam 97 between them, which reduce will be close for fusing in contact area between the second part 32 of one carrier frame plate 22
The heat and time that seal ring 28 and the first carrier frame plate 22 link together required.As described above by the first flange 76 and the first support
Frame plate 22 links together the torsional strenght also increased between sealing ring 28 and the first carrier frame plate 22.As described above by first
Flange 76 and the first carrier frame plate 22 link together also make peripheral part relatively fewer be exposed to heat, this is by being avoided making week
Enclose the durability that part is subjected to distortion relevant to heat and stress and increases recliner mechanism 18.
