In the case that the button is pressed to push the first locking bar 204 'to move toward the inside of the armrest, as shown in fig. 17 to 18, the first locking bar 204' drives the gear 203 'to rotate counterclockwise, thereby driving the second locking bar 208' to move toward the inside of the armrest, and thus, the first locking bars 204',208' are simultaneously unlocked, and the armrest is automatically opened.
As shown in fig. 19, the front-rear unlocking mechanism of the split armrest according to still another preferred embodiment of the present utility model includes a link 203", a first lock lever 204", and a second lock lever 208", wherein the pins of the first lock lever 204" and the second lock lever 208 "are moved into the 45 ° guide grooves of the link 203" to provide the link mechanism. When the button is pressed to push the first lock lever 204 "to move toward the inside of the armrest, as shown in fig. 20 to 21, the first lock lever 204" drives the link 203 "to move in a direction perpendicular to the first lock lever 204" (i.e., the lock lever 204 "extends in the front-rear direction, the link 203" is restricted to move in the left-right direction), thereby driving the second lock lever 208 "to move toward the inside of the armrest, and thus, the front first lock lever 204",208 "is simultaneously unlocked, and the armrest is automatically opened.
The front and rear side-to-side opening provided by the above three embodiment locks are controlled by the front first lock mechanisms 2,7, respectively, so that the armrest unlock can be simultaneously opened by the front and rear buttons 307. The turntable mechanisms 203, 204, 208, the rack and pinion mechanisms 203',204',208 'and the link mechanisms 203',204',208' are used to connect the front first lock rod to move in opposite directions, so as to achieve the purpose of synchronously triggering the front and rear lock bolts 303 to be in linkage unlocking. The button 307 acts on the left and right lock bolts simultaneously, and can connect the unlocking mechanisms of the left and right armrests 5, 10, thereby achieving the effect of simultaneous operation of the left and right armrests 5, 10.
The foregoing description is only a preferred embodiment of the present utility model, and is not intended to limit the scope of the present utility model, and various modifications can be made to the above-described embodiment of the present utility model. All simple, equivalent changes and modifications made in accordance with the claims and the specification of this application fall within the scope of the patent claims. The present utility model is not described in detail in the conventional art.
