Definitions

  • the scope of the invention is that of nursery products, and in particular nursery devices in which a child may be placed in the upright position, such as pushchairs or reclining chairs. More precisely, the invention concerns a nursery device with a tilting chair and a seat angle that is adjustable, according to its inclination.
  • Patent document EP-99 460 003 proposes an improvement consisting of varying the angle between the back and the chair, according to the angle at which it is tilted.
  • the angle formed by the seat element and the back element of the chair, or the seat angle is around 110° , so that it forms a chair with a back.
  • the angle formed by the seat of the chair is much more open (around 160°). In this way, the child is comfortably seated when the chair is in the upright position, and laid down when the chair is in the reclined position.
  • intermediate positions may be provided.
  • the chair has the form, viewed from the side, of a deformable triangular structure.
  • the hypotenuse of this triangle is formed by the frame of the chair.
  • the two other sides are two strengthening elements (usually plastic sheets) that are articulated at their joint summit.
  • the frame is designed so that its length can be varied. The variations of this length automatically cause the angle formed by the part of the seat and the part of the back to open or to close.
  • the length of the frame is at its shortest, and in the reclined position at its longest length.
  • the frame is made of two parts, an upper part and a lower part, the upper part can telescopically enter a portion of the lower part.
  • the chair can be maintained in a given position, with the desired seat angle, by means of a set of arms joined to the pushchair chassis.
  • Such a mechanism is however relatively complex, both to assemble when making the pushchair and to use. It is particularly impractical in the case where the chair is intended to be used alternatively facing forwards or facing backwards towards the mother.
  • the chair has on each of its sides a guide part that is part of said frame parts and has an oblong slot in which a guide pin moves that is part of the other part of the frame, the movement of said guide pin in said oblong slot allowing said length of the frame to be controlled and thus the angle of the chair.
  • Another objective of the invention is to provide such a device, where the chair may be placed in the desired position simply and safely, preferably by a person remaining behind the pushchair, without the child being able to alter this position.
  • Yet another objective of the invention is to conserve the advantages of the solution described in the document EP-99 460 003, and in particular:
  • a nursery device comprising a chair including a seat and a back, articulated with respect to one another and each articulated on a frame designed to be attached to the chassis of said nursery device, characterised in that at least one of said parts of the seat is connected to said frame by means of attachments that can adopt at least two distinct positions with respect to said part of the seat and fixed with respect to said frame, so that the angle formed between said seat and said back can be modified.
  • a nursery device with a reclining chair with an adjustable seat angle is thus obtained that is more reliable and simpler than the devices of the known techniques.
  • the mechanism for tilting the chair and varying the seat angle does not use the traditional principle of a frame composed of two parts, sliding with respect to one another. This consequently avoids the disadvantages related to this principle, which is to say the risks of jamming or incorrect operation due to distortion or wear of the sliding parts, or the presence between them of foreign bodies.
  • said attachments that can be placed in at least two distinct positions are connected to the back of said seat.
  • said attachments are connected to said part of the seat by a sliding pivot type connection.
  • said frame is mounted on other of said parts of the seat by means of a pivot and the length of the frame portion running between said sliding pivot connection and said pivot connection is fixed.
  • said attachments have at least one part forming a housing for a cylindrical portion of said frame, in which said cylindrical portion is free to rotate and at least one part forming a plate that slides with respect to a guide and/or attachment element is formed on said part of the seat.
  • said sliding plate is preferably guided and/or attached by two runners.
  • said seat comprises means for indexing the position of said attachments with respect to said part of the seat.
  • the indexing means comprise at least two recesses.
  • indexing means may be envisaged in other embodiments within the scope of this invention, in particular male/female type connections.
  • the nursery device comprises locking means for said attachments with respect to said part of the seat.
  • the locking means are advantageously actuated by a single handle, at least to unlock them.
  • said handle is mounted on the upper part of said back, so as to make it possible to unlock and control the adjustment of the angle of said chair with just one hand.
  • the device of the invention is thus particularly simple and easy to use.
  • said locking means include means which automatically return them to the locked position.
  • said seat is attached to said frame, and is free to rotate at its free end.
  • said frame defines a closed perimeter that is essentially rectangular shaped.
  • said frame is mounted on a pivot on said chassis.
  • the device preferably uses two similar connection assemblies mounted on said chassis and articulated with respect to it, said connection assemblies being also mounted on a pivot on said frame, on the one hand, and on the other hand on at least one of said parts of the seat so that pivoting said frame with respect to said chassis changes the angle between said seat and said back.
  • said handle permits control of the adjustment of the position of said frame with respect to said chassis.
  • said chair can be reversed with respect to said chassis.
  • the nursery device is a pushchair.
  • the invention also concerns a chair designed to equip a nursery device such as that described above.
  • FIGS. 1 and 2 are two perspective views of a chair according to the invention, in the upright position, respectively of the front and rear;
  • FIGS. 3 and 4 are two perspective views of a chair according to the invention, in the reclined position, respectively of the front and rear;
  • FIGS. 5 to 7 are views of indexing means equipping such a chair according to the invention.
  • the invention therefore provides a new solution that allows the angle formed by the seat and the back of a chair for a nursery device to be adjusted simply and efficiently.
  • the invention may be used for other nursery devices, in particular such as for reclining seats, seats and car seats, etc.
  • the chair of a pushchair has a seat formed by a seat 1 and a back 2 , articulated with respect to one another, such that the angle between the seat and the back may be modified between two configurations, one in which the child is in an upright position and the other in which the child is in the reclined position.
  • Such a chair also comprises a frame 3 on which are mounted via pivots the seat 1 and the back 2 as explained below.
  • This frame 3 essentially defines a rectangular perimeter and is designed, according to one advantageous embodiment, to be fixed to the chassis of a pushchair.
  • a cylindrical portion of the frame 3 is housed so that it can rotate freely in a housing 4 that is attached to a plate 41 , that can slide along runners 21 formed on the back 2 .
  • the housing 4 and the plate 41 thus form attachments which can adopt, according to one aspect of the invention, distinct positions with respect to one of the parts of the seat (in this case the back), while having a fixed position with respect to the frame 3 .
  • Such a connection, of the sliding pivot type allows the angle between the back 2 and the seat 1 to be modified, without any need for a telescopic frame. It can indeed be noted that the length of the frame portion running between the sliding pivot connection of the back 2 and the pivoting connection of the seat 31 is fixed.
  • the attachments connecting the frame 3 and the back 2 may be also or alternatively be fitted between the frame 3 and the seat 1 .
  • a handle 5 is mounted on the upper part of the back 2 , thus permitting the user to unlock and adjust the angle of the chair with one hand.
  • FIGS. 5 and 6 are views of means for indexing the position of the plate 41 , and therefore of the housing 4 , with respect to the back 2 .
  • the device is in the locked position, the handle 5 in the rest position. It is locked by means of locks 52 actuated by means of pins 521 which can move inside of angled slots 511 .
  • the locks 52 and the pins 521 are joined to one another so that movement of the pins 521 also causes the locks 52 to move.
  • the pins 521 and locks 52 are mounted on the plate 41 , but are moveable with respect to the plate 41 .
  • the handle 5 is pulled upwards, which causes the pins 521 to move in the slots 511 , from their position in FIG. 5 to their position in FIG. 6.
  • the pins 511 move towards one another, in order to release the locks 52 of the slides 411 and runners 21 .
  • the plate 41 can then slide freely with respect to the back 2 .
  • the chair can thus be tilted and the seat angle adjusted to the various possible positions, with the locked position at the desired angle being obtained by simply releasing the handle 5 , which automatically returns to the position illustrated in FIG. 5 via recall means 53 (e.g. springs or other suitable return mechanism) to which it is attached.
  • recall means 53 e.g. springs or other suitable return mechanism
  • the slides 411 of the plate 41 have recesses 412 and the runners 21 have corresponding recesses that form housings for the locks 52 .
  • the handle 5 allows, with just one hand, the plate to be unlocked with respect to the back and then, by holding the handle 5 pulled upwards, to change the angle of the chair as well as the seat angle.
  • points 4 , 31 , 7 and 63 therefore define a deformable quadrilateral, permitting the chair to be adjusted according to the invention.
  • the user can at any time release the handle in an intermediate, this being facilitated by the presence of indexing means.
