Abstract

A motor vehicle rear seat comprises a backrest having at least one portion (3) whose frame is hinged to the bodywork of the motor vehicle about an approximately vertical axis (8) adjacent to the corresponding side of the backrest.

Description

"Motor vehicle rear seat with backrest comprising at least one portion that can be rotated about a lateral vertical axis"
The present invention relates to motor vehicle rear seats of the type comprising a backrest having at least one portion that includes a frame connected in a hinged manner to the bodywork of the motor vehicle and movable between a normal operating position and a rotated position in which the luggage space of the motor vehicle is increased.
In the prior art, seats of this type have their backrest hinged along the bottom about a horizontal transverse axis, which means that the backrest can be tilted forward to an approximately horizontal position in which its rear surface forms an extension of the floor of the boot.
The object of the present invention is to provide a seat of the type indicated at the outset which will present an alternative solution to the problem of increasing the luggage space of the motor vehicle .
In order to achieve this object, the subject of the invention is a seat of the type indicated at the beginning of this description, characterized in that the said backrest portion has its frame hinged to the bodywork of the motor vehicle about an approximately vertical axis adjacent to one side of the backrest, in such a way that the said backrest portion can be rotated about the said axis so as to move from its operating position to an inoperative position in which it is positioned vertically against one side of the passenger compartment of the motor vehicle, means being provided in order to lock the said backrest portion either in its operating position or in its inoperative position.
In a preferred embodiment, the abovementioned frame has a lower portion held in a seating on the bodywork in the abovementioned operating position and can be raised to withdraw the said lower portion from the abovementioned seating, in order to be rotated into the inoperative position. Still with reference to this preferred embodiment, the frame is supported in a hinged manner by a sleeve on a vertical axis and mounted on the bodywork, in which sleeve a cylindrical hinge component connected rigidly to the said frame is mounted so as to be able to slide and turn. Again in the case of the preferred embodiment, the hinge component is provided with a radial tooth which is guided in a slot shaped like an inverted L in the wall of the supporting sleeve. A spring is placed between a wall at the bottom of the supporting sleeve and a wall at the bottom end of the hinge component in order to tend to push the frame upwards.
Again in the case of the abovementioned preferred embodiment, the supporting sleeve is provided with a locking pin projecting radially into the interior of the sleeve in order to selectively engage in two holes in the cylindrical hinge component in the operating and inoperative positions of the frame, for the purpose of locking the frame in the said positions. The said pin has a handgrip end to enable it to be disengaged, against the action of elastic means with which it is fitted, from its locked position.
The backrest preferably has two separate portions each hinged about its own approximately vertical axis adjacent to its particular side of the backrest . Clearly, the details of construction and the embodiments may vary greatly from those indicated above, provided that the principle of the invention lies m the hinging of the backrest portion about a lateral vertical axis.
Other features and advantages of the invention will become apparent m the course of the description which follows, given with reference to the attached drawings, supplied purely by way of non-restrictive example, m which:
Figure 1 is a perspective view of a motor vehicle rear seat according to the invention,
Figure 2 is a side view of the seat shown m Figure 1, Figure 3 is a perspective view on an enlarged scale of the frame of a portion of the backrest of the seat according to the invention,
Figure 4 is a view on an enlarged scale of the hinge of the frame shown m Figure 3, and Figure 5 is another view on an enlarged scale of the locking pin located on the hinge shown m Figure 4.
In the drawings, the number 1 indicates the whole of a motor vehicle rear seat comprising a sitting part 2 and a backrest that includes two separate backrest portions 3 (only one of which can be seen m the drawings) . Each backrest portion 3 comprises a padded cushion 4 fixed to a frame 5. In the case of the example illustrated, the frame 5 consists of a tubular component shaped approximately like an inverted L to which the cushion 4 is attached by means of a series of quick-attachment mountings 6. At its upper end, the tubular component 5 is connected rigidly to a cylindrical hinge component 7 which rotates about an approximately vertical axis 8 inside a cylindrical sleeve 9 (see Figure 4) . The cylindrical sleeve 9 is welded to a bracket 10 which is fastened, e.g. by means of screws 11, to the bodywork of the motor vehicle in a position such that the sleeve 9 is adjacent to the corresponding side of the backrest. The bracket 10 is also used to support the seat belt retractor.
As can be seen clearly in Figure 3, in a position of normal use of the backrest portion 3, the lower end 12 of the tubular component 5 fits into a cup seating 13 belonging to a bracket 14 welded to the motor vehicle bodywork. From this position the frame 5
(and with it the cushion 4) can be lifted vertically until the end 12 is out of the cup seating 13, and then rotated about the axis 8 until the backrest portion 3 is in the position illustrated in Figure 1, in which it is placed against the corresponding side of the passenger compartment of the motor vehicle, thus increasing the luggage space. Still with reference to the example illustrated, the frame 5 also incorporates a basket 15 having a net structure connected rigidly to the tubular component 5.
The cylindrical hinge component 7 is fitted with a radial tooth 16 which slides in a slot 17 (shaped like an inverted L in the wall of the sleeve 9) in such a way as to guide the initial movement in a vertical direction and the subsequent rotary movement of the backrest portion 3 to move it from the position of normal use to the inoperative position illustrated in Figure 1. To facilitate the operation of lifting the backrest, a helical spring 18 is placed inside the sleeve 9 between the lower end of the cylindrical hinge component 7 and a stop wall 19 fixed to the sleeve 9.
The backrest is provided with means for locking the mobile portion 3 either in its position of normal use or in the inoperative position illustrated in Figure 1. To this end there is rigidly connected to the sleeve 9 a radial cylindrical body 20 inside which slides a radial peg 21 which projects into the sleeve 9 through a hole formed in the sleeve 9 (not shown) . This peg can be engaged in two holes (also not shown) formed in the hinge component 7 at positions corresponding to the position of normal use and the inoperative position of the backrest portion 3. The outward end of the peg 21 is rigidly connected to a knob 22 which is pulled radially inwards by a helical tensioning spring 23.
When it is wished to move the backrest portion 3 from its position of normal use to the inoperative position illustrated in Figure 1, the knob 22 must first be grasped and pulled so as to disengage the peg 21 from the hinge component 7, against the force of the helical spring 23. Once it is disengaged, the backrest can be moved vertically upwards, assisted by the spring 18 until the pin 16 reaches the top end of the vertical section of the inverted L slot 17. Having reached this raised position, in which the lower end 12 of the frame 5 is out of the seat 13, the backrest portion 3 can be rotated into the inoperative position illustrated in Figure 1, where the peg 21 springs back into the corresponding hole in the hinge component 7. Naturally, the backrest portion 3 which is not illustrated in the drawings in hinged about an axis parallel to the axis 8 and adjacent to the left-hand side of the backrest, so that the back portion can be moved up against the left-hand side of the passenger compartment of the motor vehicle.
In the rotated position of either or both of the backrest portions, the capacity of the luggage space is increased.
Clearly, without affecting the principle of the invention, the embodiments and the details of construction can vary greatly from what has been described and illustrated purely by way of example, without thereby departing from the scope of the present invention.
