Definitions
- the present invention relates to a vehicle seat, with mechanisms that allow the backrest to be folded back and slightly raise the seat cushion to determine a horizontal surface that can eventually be used as a bed.
- the object of the invention is to provide means materialized in a small number of parts that duly associated structurally and functionally, in their application to the seat of a vehicle, allow to transform said seat into a bed as a result of the folding back of the backrest and A slight upward elevation of the seat cushion determines a perfectly flat surface for use as a bed.
- the US patent 6135558 can be cited, in which between the seat cushion and the backrest itself an arc-shaped piece arranged as a connecting rod arranged in the backward folding of the backrest carries with it the tilting of that piece and consequently the elevation of the rear part of the cushion, which is also raised by its front part by means of a set of connecting rods articulated with each other and articulated both to the cushion and to the fixed structure of the seat.
- the mechanism is complemented with locking means to maintain stability both in the normal use position of the backrest and the folding position of the backrest, in order to ensure that these positions are stable as just stated.
- the mechanism has drawbacks such as the need for two connecting rods with their corresponding joints to raise the front part of the cushion in the rearward folding of the backrest, as well as the need to use a kind of articulated connecting rod to relate the cushion to the backrest, regardless of how unreliable the arching means are in the stable resting and folding positions.
- Other mechanisms are described in documents such as the German patent DE 10035256 Cl, the US patent 4268086, the European patent EP 0628445 Al, among others, although all of them have the disadvantage that the mechanisms to get the seat of the corresponding vehicle to be transformed in a bed, they are complex to be constituted by numerous pieces with the inconveniences that this entails.
- the seat for vehicles convertible into bed that is recommended, has been designed to solve the above-mentioned problem, based on a simple mechanism, since it is determined by a minimum number of parts that not only allow the backrest to be folded back and in turn raise Simultaneously and slightly the seat cushion to determine a horizontal surface, but is achieved by a simple bolt, formed by a tilting piece, lock the backrest in both positions, of folding and verticality, keeping them in that position unless it is act intentionally on that piece in bolt functions.
- the mechanism applicable to the seat for vehicles object of the invention is characterized in that the backrest is attached to the seat structure through an axis with respect to which said backrest can rotate, while the latter is related to the cushion by means of another axis of rotation that allows the swinging or free rotation of one with respect to the other at that point of articulation of both elements (backrest and cushion).
- the structure of the backrest has a part, in which the articulation axis with the cushion is precisely established, which is located, in the rest position for that, under the rear part of the cushion, so that the rearward folding of said backrest It carries with it the thrust and in turn the elevation of the cushion, which in its front part is related to a connecting rod articulated on one side to the cushion itself and on the other to the fixed structure of the seat, this structure that in addition to supporting all the loads will have support elements that perform the function of stop or end of stroke when one of the two final positions is reached and corresponding to the seat function itself, and to the bed function in the transformation of that.
- the means that allow to transform the seat of a vehicle into a bed are constituted by a minimum number of parts, with a simple and also safe functionality in the stable positions that can occupy the set when the vertical backrest fulfilling the functions of the seat itself, or when the backrest is placed horizontally with the elevation of the seat, corresponding to the transformation into a bed.
- Figure 1 shows a sectional side view of the seat assembly of a vehicle in the rest position.
- Figure 2. It shows another view in side section, but in this case with the seat assembly transformed into a bed, by folding back the backrest and small elevation of the seat cushion.
- the seat for vehicles object of the invention convertible into a bed and which includes a backrest (1) and a seat cushion (2) as conventional, has the particularity that the structure ( 3) of the backrest (1) is articulated mounted on the fixed structure of the seat assembly through a pivot shaft (4), while the structure (5) of the cushion
- connecting rod (7) which, at one end, is articulated, through the axis of rotation (8), to the structure (5) of the cushion (2), while at the other end, the mentioned connecting rod (7) is articulated, by means of the axis (9), to the general and fixed structure (6) of the seat assembly, that connecting rod (7) being located in correspondence with the anterior part and below the own cushion (2), as clearly represented in the figures.
- the backrest (1) in addition to the axis of rotation (4) for said backrest and the axis of rotation (10) or of articulation with respect to the cushion, it comprises a pair of bolts (11) and (12) in which a tilting part (13) can be interlocked in functions of a bolt that is pivotally mounted on the general structure of the seat through a rotation axis (14), so that that part in function of a bolt (13) is provided of a pair of recesses (15) and (16) that according to the position of the backrest (1) will determine positioning means for the bolt (11) or bolt (12), respectively, and determine the means of locking and immobilization of the backrest in either of the two positions, that is to say of rest as represented in Figure 1, or when it has been transformed into a bed as shown in Figure 2.
- the structure (3) of the backrest (1) extends below and behind the seat cushion (2), determining an end portion (17) in which both the locking bolt (11) are precisely provided in the position of resting the backrest (1) as the axis of articulation and rotation (10) between such structure (3) of the backrest (1) and the structure (5) of the cushion (2). 7.
- the seat performs its function as such, keeping the backrest (1) stable and locked in that position by means of the bolt-working part (13) that is it locks into the bolt (11) of the structure (3) of said backrest (1), preventing it from collapsing backwards.
- the backrest (1) or what is its structure (3), can be folded back, a dejection that carries the backrest thrust on the structure (5) of the cushion (2), producing the displacement of the cushion and in turn a slight upward elevation of the rear, while under the connecting rod (7) related to the structure (5) of the cushion ( 2) and with the fixed structure (6) of the seat, that connecting rod (7) tilts and produces the elevation of the front part of such cushion (2), achieving continuity surface between the cushion (2) and the backrest (1) as shown in figure 2, so that in this position the bolt (12) of the structure (3) of the backrest (1) is locked in the recess (16 ) of the bolt (13), remaining stable in that position until a new intended release of the bolt itself (13) with respect to such bolt (12) is not carried out.
