Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Hereinafter, an embodiment of the invention will be described, in order to allow the latter to be better understood, by way of non-limiting example and with reference to the accompanying drawings, wherein:

[0014] FIG. 1 is a plan view of a convertible motor vehicle comprising a motor vehicle seat according to an embodiment of the invention,

[0015] FIG. 2 is a side view, with parts removed for greater clarity, of the seat of FIG. 1, and

[0016] FIGS. 3 and 4 are similar to FIG. 1 and show the seat in two respective operating conditions distinct from the one of FIG. 2.

EMBODIMENTS OF THE INVENTION

[0017] In FIG. 1, reference number 1 is used to indicate, as a whole, a motor vehicle. More precisely, the motor vehicle 1 is a convertible motor vehicle.

[0018] Hence, the motor vehicle 1 comprises a passenger compartment 2 and a roof 3, which can be configured between an open configuration, in which the passenger compartment 2 is open to the outside, and a closed configuration to close the passenger compartment 2, in particular when all the other openings of the motor vehicle 1 are closed (for instance, windows, openings of the doors or of the trunk).

[0019] According to an alternative, the passenger compartment 2 could always be open to the outside; in other words, the motor vehicle 1 could lack the roof 3.

[0020] Furthermore, the motor vehicle 1 comprises a seat 4, in particular a rear seat, more in particular a bench seat.

[0021] The seat 4 comprises a plurality of bodies or portions 5, 6, 7, the portion 6 defining at least a backrest portion, specifically the entire backrest.

[0022] The portions 5 and 7 may, for example, be fixed; more in particular, the portion 5 defines a headrest.

[0023] The portion 7 extends along the forward moving direction of the motor vehicle 1, namely along a horizontal direction, thus defining a base of the seat 4 suitable for supporting the legs of a passenger seating on the seat 4.

[0024] Furthermore, the seat 4 comprises a mechanism 8 configured to couple the portion 6 to the portion 5 in a movable manner between a first and a second position.

[0025] In the first position, shown in FIG. 2, the portion 6 is arranged between the portions 5, 7 and is transversal to the portion 7, more precisely approximately orthogonal. In other words, the portion 6 extends in a substantially vertical manner in the first position. In this position, the seat 4 is suitable for supporting the passenger seating with the lower limbs resting against the portion 7 and the back resting against the portion 6 in the area of a surface 9 of the portion 6 itself.

[0026] In the second position, the portion 6 extends along the horizontal direction above the portion 7. In other words, the portion 6 has a surface 10 opposite the surface 9 and facing the portion 7.

[0027] In the second position, shown in FIG. 3, the portion 6 becomes a wind deflector, at least when the roof 3 is in the open configuration. Namely, the portion 6 deflects an air flow directed towards the passenger compartment 2 towards the outside. More precisely, the air flow starts from a rear area of the motor vehicle 1 towards the passenger compartment 2. Here, the air flow meets the portion 6 in the second position brushing the surface 9, which is designed to support the back of the passenger in the first position.

[0028] In particular, the portion 6, in the second position, is tilted upwards relative to the horizontal direction, more in particular at an acute angle. In the embodiment shown in FIG. 3, an end 11 of the portion 6, more distant from the portion 5, reaches a height equal to or greater than the higher end 12 of the portion 5.

[0029] More in detail, the mechanism 8 consists of a hinge, so that the portion 6 is hinged to the first body 5 in a rotary manner in order to rotate around an axis H between the first and the second position. In particular, the axis H is horizontal and orthogonal to the forward moving direction of the motor vehicle 1.

[0030] Preferably, the mechanism 8 is manually operated. Alternatively, the mechanism 8 could also be electrically operated.

[0031] Furthermore, the seat 4 comprises a frame portion 14. In the first position, the portion 6 is arranged between the end 11 and an end 15 of the frame portion 14.

[0032] In other words, the frame portion 14 extends behind the seat 4 and, hence, behind the portion 6, both in the first and in the second position. Namely, the frame portion 14 extends on the opposite side of the portion 7 relative to the portion 6 in the first position.

[0033] Preferably, the seat 4 comprises a locking device 16, which is configured to fix the portion 6 to the frame portion 14 with the portion 6 in the first position. For example, the locking device 16 can be closed in a snapping manner and be released by hand, for instance through a lever or a button or through a key. Alternatively, the locking device 16 can be closed by hand, as well. Possibly, the closing and/or the opening of the locking device 16 can be electrically operated.

[0034] More preferably, the seat 4 further comprises a dividing wall 17 coupled to at least one of the portion 5 and the frame portion 14 in a movable manner between a separation position and a communication position.

[0035] In the separation position, shown in FIG. 3, the dividing wall 17 is arranged between the portion 5 and the frame portion 14. More in detail, the dividing wall 17 is arranged behind the portion 6 in the first position. In this position, the dividing wall 17 separates a space ahead or in front of the seat 4 from a space at the back of the seat 4, for example defined by a trunk of the motor vehicle 1. In particular, the dividing wall 17 extends in a substantially vertical manner from the point in which it rests against the portion 5 up to the point in which it is coupled to the frame portion 14. The latter defines at least one wall of the trunk.

[0036] In the communication position, shown in FIG. 4, the dividing wall 17 frees a space between the portion 5 and the frame portion 14, such as to allow objects to be moved from the front of the seat 4 to the back thereof, at least when the portion 6 is in the second position.

[0037] Specifically, the dividing wall 17 is coupled to the frame portion 14, in particular is hinged to the latter in a rotary manner around a horizontal axis H1 orthogonal to the forward moving direction of the motor vehicle 1, and rests against the portion 5 in the separation position.

[0038] For example, in the communication position, the dividing wall 17 can be arranged on the portion 7. Here, in particular, the dividing wall 17 faces the surface 10, when the portion 6 is in the second position. More in particular, the dividing plate 17 is arranged between the portions 6, 7.

[0039] Alternatively, in the communication position, the dividing wall 17 could rest on the portion 14.

[0040] In other words, the dividing wall 17 could be rotated in a clockwise or counterclockwise direction.

[0041] Furthermore, the dividing wall 17, in the separation position, faces the surface 10 with the portion 6 in the first position.

[0042] Owing to the above, the advantages of the seat 4 according to the invention are evident.

[0043] The seat 4 is multiuse, in that it can be used both as a seat and as a wind deflector; in this way, no removable wind deflector is needed and no storage compartment is needed to accommodate the wind deflector when it is not used. This corresponds to significant reduction in the space taken up in the motor vehicle 1.

[0044] Furthermore, the use of the seat 4 as wind deflector is extremely simple. Users only have to handle the portion 6, for example releasing the locking device 16 and moving the portion 6 to the second position. Here, users can fix the second position of the portion 6 to a component of the motor vehicle 1, for example through a further locking device which is not shown herein.

[0045] Furthermore, the handling of the portion 6 also allows for a communication between the front of the seat 4 and the back thereof in a simple fashion. In this way, the space of the trunk can be increased, for example in order to introduce large-sized objects and retrieve or store objects starting from the passenger compartment 2.

[0046] The diving wall 17 allows users to choose whether to maintain the communication between front and back or the seat 4 or not, depending on the needs, in a simple fashion.

[0047] Finally, the seat 4 according to the invention can be subjected to changes and variants, which, though, do not go beyond the scope of protection set forth in the appended claims.
