Definitions
- the invention relates to a convertible into a bed, the seat and back cushions are connected to one another by a joint having a joint, by means of which the seat cushion can be swiveled up, so that access to a bedding space arranged in the furniture frame is possible, and the furthermore allows the seat and back cushions to be moved into a common lying plane, a locking arm provided with a catch and a pawl being provided which interacts with a pin holding the seat cushion in its raised position.
- the seat If the seat is converted into a bed, you first raise the seat cushion and bring it into an almost vertical position. Due to the sequence of movements, the upright back cushion is also pivoted and brought into a lying position. He is supported on the rear wall of the bedding room. Since the seat cushion is still in the vertical position, access to the bedding room is possible. Only after unlocking the seat cushion can be swiveled into the horizontal position and is supported on the front panel of the bedding room. The lying position is now reached. If the vertical seat cushion is moved further in the intermediate position and the angle between the seat cushion and the back cushion is reduced, the Lock unlocked. However, if the position of the seat cushion relative to the back cushion is reduced beyond the seat angle, the cushions are pressed against one another in the pivoting area of the fitting. If the furniture is heavily upholstered, this makes it difficult to use when converting. Do you lift the when converting from the sitting to the lying position
- a tension spring which acts on the rear rocker on the one hand, and on the web of the fitting on the other, and facilitates the pivoting movement of the seat cushion when converting, makes it difficult to change the angle and thus unlock the lock, but avoiding this malfunction is prevented by the arrangement of this tension spring not ensured.
- the invention has set itself the goal of creating seating and reclining furniture in which the described malfunctions are practically excluded.
- stops which determine the seat angle and prevent its reduction are arranged according to a further feature of the invention.
- FIG. 1 shows the furniture in a partially cut Side view in sitting position and Figure 2 on an enlarged scale the associated fitting.
- 3 shows the furniture in the intermediate position and FIG. 4 shows the associated fitting on an enlarged scale;
- 5 shows the furniture in the lying position and
- FIG. 6 shows the associated fitting on an enlarged scale;
- 7 is a side view of the area around the stops in the direction of line VII in FIG. 2nd
- a piece of furniture has a seat cushion 1 and a back cushion 2, which are pivotally connected to one another via axes 3.
- the axes 3 connect boards 4 and 5, which are connected to the pads 1 and 2 and thus form part of these pads.
- the two webs 8 are attached to both side walls of a bedding space 9 forming the furniture frame.
- Stops 16 and 17 between the back cushion 2 (board 4) and the seat cushion 1 (board 5) are designed and arranged such that the intended seat angle of the furniture cannot be fallen below.
- a locking arm 10 is articulated on the rear rocker 6 near its connection to the circuit board 4 of the back cushion 2. This locking arm 10 is supported on its opposite end region by means of a catch 11 on a pin 12 which is attached to the circuit board 5 of the seat cushion 1.
- the locking arm 10 is designed so that the intended seat angle is fixed in the locked position in the sitting position.
- a pawl 13 on the locking arm 10 allows covering the latch 11 and thus unlocking the locking arm 10.
- a spring 14, which acts between the locking arm 10 and the circuit board 4, ensures that the locking arm 10 is pressed against the pin 12. Furthermore, a spring 15 is usually suspended between the web 8 and the rocker 6.
- the pawl 13 has released the catch 11 of the locking arm 10.
- the locking arm 10 is latched onto the pin 12 with this catch 11 and locks the back cushion 2 with the seat cushion 1, the two pads enclosing the desired seat angle.
- the stops 16 and 17 which are not visible in FIGS. 1 and 2 and which act between the back cushion 2 and the seat cushion 1 prevent a reduction in this seat angle. When converting the furniture into the intermediate position, it is therefore not possible to reduce the seat angle by lifting the seat cushion 1, an undesired unlocking is thereby avoided.
- Fig. 3 shows the furniture in the intermediate position.
- the back cushion 2 is brought into the lying position and is supported on the rear wall of the bedding room 9.
- the seat cushion 1 is raised and is held in this position by the locking arm 10 locked with the pin 12.
- the seat cushion 1 was pivoted further counterclockwise, this movement being limited by the stops 16 and 17 until the seat angle is reached. During this movement, however, the pin 12 slides out of the catch 11 of the locking arm 10 and moves over the pawl 13. When the seat cushion 1 is then lowered, the pin 12 is guided by the pivoted pawl 13 over the catch 11 of the locking arm 10 and the seat cushion 1 can be lowered and placed on the front panel of the bedding compartment 9.
