Definitions
- the invention relates to devices which are responsible for locking / unlocking the rotation of the folding backs of certain motor vehicle seats.
- Some motor vehicles are equipped with a seat provided with a seat (or bench) to receive several passengers and two neighboring folders, foldable independently and frame.
- the relative dimensions of the backs of this type of seat can be 1 / 3-2 / 3 or 60% -40% or 1 / 2-1 / 2, for example.
- These folding folders are intended to allow modularity of the storage space of a motor vehicle.
- Each file is generally associated with a locking / unlocking device which is responsible for securing it to an element of its vehicle, such as the rear shelf cross member, to prevent it from being rotated forwards. or to separate it from this element in order to allow it to be rotated forward and thus folded against the upper face of the seat.
- a locking / unlocking device which is responsible for securing it to an element of its vehicle, such as the rear shelf cross member, to prevent it from being rotated forwards. or to separate it from this element in order to allow it to be rotated forward and thus folded against the upper face of the seat.
- the invention therefore aims to provide a simple alternative solution, inexpensive and relatively compact.
- a device dedicated to the locking / unlocking of two adjacent folders, foldable and frame of a seat of a motor vehicle, and comprising a shaped rod which is intended to be rotatably mounted on a vehicle element at a location which is located in the immediate vicinity of two adjacent retaining portions of the armatures when the latter are in the upright position, so as to assume a locking position, in which it prevents a forward rotation of the one and / or the other of the two folders by retaining the retaining part of his / their armature (s), or an unlocking position, in which it allows a forward rotation of one and / or the other both files by release of the restraining part of his / their armature (s).
- the locking device according to the invention may comprise other features that can be taken separately or in combination, and in particular:
- Its shaped rod can be arranged to retain in its locking position two armature retaining portions which are each arranged in the form of at least one structural bar;
- its shaped rod may be arranged to retain in its locking position two retaining portions of the reinforcements which are each arranged in the form of an insert;
- each insert can be arranged to retain in its locking position a portion of each insert which is substantially U-shaped, possibly reversed, and installed in a substantially vertical plane;
- its shaped rod may comprise two terminal parts and a central connecting part which together define a U and which are intended to frame at least a portion of the two reinforcement holding parts in its locking position, each of these end portions having a end intended to be rotatably mounted relative to the element of the motor vehicle, and the central portion being intended to retain the two retaining portions of the armatures in the locking position by prohibiting their rotation forward;
- its shaped rod may comprise an end portion and a central portion which together define a T, the central portion having an end intended to be rotatably mounted relative to the motor vehicle element so as to be driven in rotation between the two reinforcing portions of the reinforcements, and the end portion comprising two sub-parts intended respectively to retain the two retaining portions of the reinforcements in the locking position by preventing their rotation towards the front;
- its shaped rod may be designed to be rotated either downwards (respectively upwards) in order to be placed in its locking position or upwards (respectively downwards) in order to be placed in its position of unlocking.
- the invention also proposes a motor vehicle comprising (at least) a seat with two adjacent folders, foldable and frame, and at least one locking device of the type shown above.
- Such a motor vehicle may for example comprise an element which constitutes a rear shelf cross member and on which is mounted rotatably the shaped rod of the locking device.
- FIG. 1 diagrammatically and functionally illustrates, in a perspective view, a motor vehicle seat with two folding backs and equipped with a first example of a locking device according to the invention placed in a locking position

- D locking / unlocking device
- SI seat
- ADj type folding and armature
- FIGS. 1 to 5 show schematically and functionally an example of a motor vehicle seat SI equipped with a locking / unlocking device D according to the invention.
- the relative dimensions of the first DS1 and second DS2 folders are of type 1 / 3-2 / 3. But, the relative dimensions could also be of type 60% -40% or 1 / 2- 1/2, for example.
- Each armature ADj comprises, for example and as illustrated, metal structural bars BS which define a resistant frame and on which is mounted a lining (not shown).
- the AS seat is secured to the floor of the vehicle.
- the first DS1 and second DS2 backrests can be freely rotated on a raised part of the vehicle floor or on the AS seat.
- the (locking) device D comprises at least one shaped rod TC which is intended to be rotatably mounted on an element TP of the motor vehicle which is situated in the vicinity of the reinforcements ADj when they are in the upright position (see FIGS. ).
- the element TP is considered to be the rear shelf cross member which supports the rear shelf and transversely stiffens the vehicle structure at the interface between its passenger compartment H and its rear boot. CR. But, the invention is not limited to this type of element.
- This shaped rod TC is more specifically intended to be rotatably mounted on the element TP at a place which is situated in the immediate vicinity of two retaining portions PAj of the armatures ADj which are adjacent when they are both in an upright position (that is to say, allowing a passenger to sit).
- This rotational assembly is intended to allow the manual positioning of the shaped rod TC either in a locking position or in an unlocked position.
- locking position is understood here to mean a position in which the shaped rod TC prevents the forward rotation of the first backrest DS1 and / or the second backrest DS2 by retaining the corresponding retention portion PAj of its / their armature ( s) ADj. This locking position is illustrated in FIGS. 1 and 3 to 5.
- unlocking position is understood to mean a position in which the shaped rod TC allows the forward rotation of the first backrest DS1 and / or the second backrest DS2 by release of the corresponding portion PAj of its / their armature (s) ADj. This unlocking position is illustrated in FIG.
- the shaped rod TC is operable from the inside of the rear trunk CR and placed in its locking position and that we want to unlock the first folder DS1 and / or the second folder DS2 in order to (s) down against the upper surface of the AS seat, just train Manually the TC-shaped rod rotated downwardly to place it in its unlocking position which releases the PAj retaining portions of the first DS1 and DS2 second folders.
- This situation is illustrated by the arrow F1 'of FIGS. 3 and 5. It then remains only to push forward the first folder DS1 (arrow F2) and / or the second folder DS2 (arrow F3).
- the retaining portions PAj are all inserts that are secured to the armatures ARj, for example by welding (or bonding).
- the retaining portions PAj reported are possibly (initially) part of the device D. But, it is conceivable that these retaining portions PAj form an integral part of the armatures ARj.
- at least one of the structural bars BS of each armature ARj is shaped so as to define a retaining part PAj.
- the shaped rod TC is arranged to retain in its locking position a portion PR of each insert PAj.
- This portion PR is here substantially U-shaped inverted and installed in a substantially vertical plane. It (PR) is for example made by folding or shaping a metal rod.
- the shaped rod TC comprises here, without limitation, two terminal portions PT and a central portion PC of connection which define together a U, substantially. As illustrated in FIG. 1, these two end portions PT and this central part PC are intended to frame at least each portion PR of the two retaining portions PAj of the frames ADj when the shaped rod TC is in its locking position.
- Each of the two end portions PT has a first end which is secured to one of the two opposite ends of the central portion PC, and a second end which is intended to be rotatably mounted relative to the element TP of the motor vehicle. It will be understood that it is the central portion PC which is more precisely intended to retain the two retaining portions PAj of the armatures ADj, via their portions PR, in the locking position by preventing their rotation forward, because it is placed in front of said portions PR.
- This first exemplary embodiment is well adapted to an actuation of the shaped rod TC by the interior of the passenger compartment H.
