The specific embodiment
Hereinafter, identical Reference numeral refers to components identical.
Fig. 1 illustrates the decomposing schematic representation according to release of the present utility model termination pillow guide pin bushing 100.Release termination pillow guide pin bushing 100 comprises locking compressing tablet 101, guide pin bushing body 102, retracing spring 103, unlock button 104, guide pin bushing cap 105, locking cross bar 106 down.Wherein, following locking compressing tablet 101, retracing spring 103, unlock button 104, guide pin bushing cap 105, locking cross bar 106 all can integratedly be installed in 112 places, upper surface of guide pin bushing body 102.As shown in Figure 1, following locking compressing tablet 101 directly is enclosed within the groove of character pair shape of guide pin bushing body 102 bottoms, and upper surface 112 and following locking compressing tablet 101 are in the opposite end of guide pin bushing body 102.Following locking compressing tablet 101 plays in guide pin bushing body 102 lower ends assists fixedly that guide pin bushing 100 plays the auxiliary positioning effect in addition to the effect of cushion frame when mounting guide sleeve 100.
Fig. 3 illustrates the generalized section according to release of the present utility model termination pillow guide pin bushing 100.As shown in Figure 3, removed guide pin bushing block 105, in the spring mounting hole 107 of the upper surface of retracing spring 103 embedding guide pin bushing bodies 102.The spring 103 of one or more spring mounting holes 107 to hold respective amount can be set.Yet, preferably, as shown in Figure 3, be the consideration of balance, in described upper surface, be provided with two spring mounting holes 107.Unlock button 104 is provided with two projectioies 109.Spring 103 1 ends withstand on the inwall of spring mounting hole 107, and the other end is withstood by projection 109, and like this, projection 109 just is pressed into retracing spring 103 in the spring mounting hole 107.
From Fig. 1 and 3 all as seen, unlock button 104 takes the shape of the letter U, and comprises two legs 108.Locking cross bar 106 is across space in the U-shaped of unlock button 104, and two ends are separately fixed at two leg 108 places.The cross-sectional plane of this locking cross bar 106 can be the shape of any appropriate, is preferably circle.As shown in Figure 3, when projection 109 was pressed into spring mounting hole 107 with retracing spring 103, locking cross bar 106 strode across through hole 111.
In addition, end at two legs 108 of unlock button 104 has a barb part 110 respectively, described barb part 110 can be hooked the upper surface of guide pin bushing body 102, thereby whole unlock button 104 is embedded in the mating holes of described upper surface, and then cover upper guide bush cap 105.At this moment, locking compressing tablet 101, retracing spring 103, unlock button 104, guide pin bushing cap 105, the locking cross bar 106 integrated upper end surfaces that are installed in guide pin bushing body 102 have just been realized to descend.
Fig. 4 illustrates the contour structures scheme drawing according to release of the present utility model termination pillow guide pin bushing.
In operation, when needs move downward the relative seat of headrest, just need inwardly push unlock button 104, then retracing spring 103 is further inwardly compressed into spring mounting hole 107, meanwhile locking cross bar 106 also is pushed thereupon, thereby, and then make in the U-shaped of through hole 111 and unlock button 104 and connect fully between the space no longer across through hole 111.In this case, will rest the head on when pressing down, owing to there be not stopping of locking cross bar 106, headrest just correspondingly moves downward.When headrest drops to suitable height gear, unclamp unlock button 104, retracing spring 103 resiliences, thus drive release cross bar 106 rollbacks and snap in the headrest stem guiding trough, make locking cross bar 106 again across mistake through hole 111, and then make headrest recover lockup state.
When needs are held the headrest upward movement, because locking cross bar 106 is in the top of through hole 111, therefore can't play inhibition to through hole 111, therefore do not need by unlock button.
As shown in Figure 2, the utility model also provides a kind of locking termination pillow guide pin bushing 200.Locking termination pillow guide pin bushing 200 comprises locking compressing tablet 201, guide pin bushing body 202, retracing spring 203, locking button 204, guide pin bushing cap 205, locking cross bar 206 down equally, wherein, following locking compressing tablet 201, retracing spring 203, locking button 204, guide pin bushing cap 205, locking cross bar 206 all can integratedly be installed in 212 places, upper surface of guide pin bushing body 202.Equally whether the perforation of controlling through hole 111 by locking cross bar 206 guide pin bushing 200 that whether guarantees to rest the head on locks, and its concrete effect is to guarantee that in headrest total travel motion process headrest discord back of seat separates.Only locking cross bar 206 is pushed away under the situation of through hole 111 pressing locking button 204, headrest could be extracted.
From above describing as can be seen, the structure of locking termination pillow guide pin bushing 200 and release termination pillow guide pin bushing 100 are basic identical, difference just is button, the button 104 of release termination pillow guide pin bushing 100 is thick relatively owing to need often to use, to make things convenient for the occupant to operate, and the button 204 of locking termination pillow guide pin bushing 200 is less relatively owing to only use when guide pin bushing locks, and touches to prevent the occupant.Usually, use frequent relatively release termination to rest the head on guide pin bushing 100 and be installed in the headrest outside, and pillow guide pin bushing 200 in the locking termination of less use is installed in the headrest inboard comparatively speaking.
Fig. 5 illustrates the contour structures scheme drawing according to locking of the present utility model termination pillow guide pin bushing.
Therefore, according to as can be known mentioned above, when needs with headrest when back of seat is removed, need be pressed into the unlock button 104 of release termination pillow guide pin bushing 100 and the button 204 of locking termination pillow guide pin bushing 200 simultaneously, headrest directly could be extracted from the headrest guide pin bushing.
In addition, Fig. 6 illustrates the assembly drowing between guide pin bushing and the cushion frame.As shown in Figure 6, be positioned at the boss face 601 and cushion frame good fit in guide pin bushing stage casing, make the fitting surface of guide pin bushing and cushion frame increase, and increased guide pin bushing intensity, be subjected to the cushion frame extruding and can be out of shape, by the boss design, also be convenient to guide pin bushing and dismantle simultaneously from cushion frame.In addition, on guide pin bushing, can improve intensity and prevent the locking end and the installation of the mistake of release end by the one or more reinforced ribs of reasonable Arrangement.
In addition, as illustrated in fig. 1 and 2, two concave portions are arranged, match, improved the stability of locking, play that simultaneously guide pin bushing is fixed on effect on the seat back-rest framework with following locking compressing tablet 101 in guide pin bushing body 102 bottoms designs.
Release provided by the utility model termination pillow guide pin bushing and locking termination pillow guide pin bushing only need be pressed unlocking/locking and end button and can operate, and therefore easy and simple to handle, in light weight, good with the headrest mated condition, loading transfer is good.As shown in Figure 1, the unlock button shape is protruded, and fully meets the demand of ergonomic, and the client is easy to just can touch unlock button when the release of operation headrest.Simultaneously, the utility model can also preferably be provided with the locking button comparatively hidden, makes the client can not touch easily, thereby prevents that headrest from separating with seat under improper situation.
Those skilled in the art will also be appreciated that protection domain of the present utility model is not limited in the foregoing description, and all drop in the scope of the present utility model equivalents of the present utility model.
