Abstract

The present invention relates to a stowable armrest which may be moved from: (i) a lowered, operating position; (ii) to a raised position in which the armrest generally lies in a plane which is to the rear of and substantially parallel to a plane of the back portion of the seat; and (iii) then to a final stowed position in which the armrest is located rearwardly of the back portion of the seat. Armrest movement from the raised position to the stowed position may be accomplished while maintaining the armrest in the stowing plane.

Description

The stowable armrest of automotive seat

Invention field:

Generally speaking, the present invention relates to stowable armrest, more particularly, the present invention relates to the armrest of automotive seat, it can be received in the seat back easily, is beneficial to the turnover in area, seat back.

Background technology:

In recent years, in the automobile, particularly the space between the front chair is close to more in the truck cap.Be placed between the seat armrest and armrest on electronic machine and miscellaneous equipment increase sharply quickened this congested.The truck driver often has a district of lying for sleeping in the seat back of operator's compartment, make him be difficult to enter this district but the space is limited between seat.

The present invention is intended to solve space problem between the automotive seat of armrest permanent fixation.

Brief summary of the invention:

The present invention overcomes the shortcoming of existing armrest, and the advantage that in the past never has is provided simultaneously.

In one embodiment of the invention, for automotive seat provide a kind of armrest assembly, this armrest assembly has an armrest rest, be fit to be installed in the relatively-stationary position of seat on; And an armrest is arranged, and it has bearing end and free end, and the bearing end and the rest of this armrest are hinged.Armrest can move rearwards to the stowed position of transition from the control position that is fit to occupant's application on the seat, and this moment, armrest extended upwardly; Armrest also can be laterally moved to final stowed position towards the seat line of centers from the stowed position of this transition.

Brief Description Of Drawings:

The characteristics of the novelty of stating in the appended claims book are features of the present invention.But the present invention itself and other purpose and bonus thereof can and obtain best understanding in conjunction with the accompanying drawings referring to following explanation, in the accompanying drawing:

Fig. 1 is a fragmentary, perspective view, one embodiment of the present invention is shown in working order, promptly " puts down " the right armrest under the position, in the be connected situation of armrest shown in the local section of automotive seat previous section with seat.

Fig. 2 is the rear perspective of the armrest among Fig. 1, and the armrest that part is lifted is shown.

Fig. 3 is a rear perspective, and the armrest under the transition stowed position of lifting fully is shown.

Fig. 4 is a rear perspective, illustrate pack up fully or final stowed position under armrest.

Fig. 5 is an exploded view, and the armrest of a preferred embodiment and the part of armrest bearing are shown.

DETAILED DESCRIPTION OF THE PREFERRED.

It below is the detailed description of the preferred embodiment of the present invention.Can expect that this preferred embodiment can have alternative and improvement.On function, purposes, structure or effectiveness, do the alternative of non-intrinsically safe change or revise all included by the claim of present patent application.

At first referring to Fig. 1, constitute the armrest of the preferred embodiment of the present invention, its label is 20, be designed to can from shown in control position move to the complete stowed position of automotive seat 10 back, state as follows.

Referring to Fig. 2 and 5, armrest 20 comprises bearing end 12 and free end 24, and hinged at its bearing end 22 places by armrest mounting assembly 26.The orthodox method that mounting assembly 26 is known by the professional and technical personnel suitably is fixed on the seat 10 and its vital parts has Rocker arm 40, stub 30 and master carrier 60.

Armrest 20 usefulness orthodox methods are installed on the trunnion 30, and a locating dowel pin 31 is arranged on the trunnion 30, are used for the place angle of technical well-known process restriction armrest when its control position.

Trunnion 30 is rigidly connected with Rocker arm 40.Rotational pin 43

passes hole

41,51, and stub 50 is connected with Rocker arm 40.The other end of stub 50 inserts in the return bend 67 on the main bracket 60, and main bracket 60 comprises locating dowel pin 63, can use such as the such element of stop spring, as the spring clip (not shown), stub 50 is retained in the return bend in use.

In the operation, armrest 10 can promptly " put down " position arrives transition shown in Figure 3 backward through position shown in Figure 2 stowed position from control position shown in Figure 1.When armrest is in control position, the annular groove 62 of the groove 42 (see figure 5) engage dowel pin 63 of Rocker arm 40.Locating dowel pin 63 and stub 50 are supported armrest 20 in use by this way.

Armrest 20 can upwards rotate and forward to seat 10 back around stub 50, and this rotation can impose power upwards to the far-end 24 of armrest 20 and realize.The stub 50 that armrest 20 is rotated in the return bend 67 rotates to the cocked position of transition shown in Figure 3, rotates about 107 ° this moment in a preferred embodiment.

When being in cocked position shown in Figure 3, armrest 20 just forwards the final stowed position of seat 10 back easily to.For this reason, the shape of main bracket 60 preferably can make armrest 20 and rotary middle point thereof be positioned at the plane of seat plane back.For make armrest along laterally towards the center line movement of seat 10 and forward the final stowed position of seat back to, reply armrest far-end 24 imposes laterally power inwards.At this moment two relative flanges 44 that are positioned at Rocker arm 40 downside rotate around stub 50 and return bend 67, guarantee that armrest 20 moves to the position parallel with seat back, and the periphery of flange 44 is arc, but these peripheral two ends are played armrest and laterally rotated link stopper.

Should be understood that this disclosed preferred embodiment can make an amendment, with change armrest from control position to complete cocked position, from 107 ° of rotatablely moving to other anglec of rotation.Will be further appreciated that the hunting range of the increasing armrest that disclosed device can make an amendment, thereby can be to pack up under arbitrarily angled with horizontal angle.

Will be further appreciated that can use other mechanism realizes that armrest rotates to cocked position, shakes the position of seat back again.Such mechanism includes but not limited to ball-and-socket type joint or universal swinging gear, reaches other equivalent construction that the professional and technical personnel knows.

Above-mentioned explanation does not really want to limit the implication of word in the claim of the regulation scope of the invention.On the contrary, can do further to revise on structure, function or the effect, change and all such non-intrinsically safes that these modifications there is no in essence sexually revise all included by claim.
