Description

Title of the invention: Interior padding assembly for a helmet, and associated helmet. Technical field

[0001] The invention relates to an assembly of inner padding trim for a helmet, as well as to a helmet equipped with such an assembly of inner padding trim.

[0002] It relates more particularly to an assembly of interior padding trim comprising a detachable trim element forming an inner cheek, also called a cheek pad, which is mounted inside a helmet, on the right or left at the level of the wearer's cheeks.

[0003] The invention finds a favorite, but not limiting, application in a protective helmet for motorcyclists. Previous technique

[0004] As is known, a helmet comprises a shell inside which is mounted an inner liner, also called a liner, generally made of polystyrene. In addition, the helmet includes padding elements, such as pads, often made of foam inside a textile cover, which contribute to comfort and support of the head inside the helmet. Generally, padding elements are found on the right and left sides at the wearer's cheeks; these are called inner cheek pads or padded cushions. A padding element may also be found at the rear, at the nape of the wearer's neck.

[0005] Conventionally, the padding element comprises a cushion attached to a plastic coupling plate, which is slid and press-fitted into the gap between the shell and the inner liner. However, this solution has the major drawback of being difficult to assemble on a production line and to reposition by the user who has removed it, for example, for washing or cleaning the inside of their helmet.

[0006] Documents EP2022358 and EPI 151684 propose solutions based on clips or interlocking pins (also called studs) attached to the shell, in notches provided on the coupling plate attached to the bearing. While these solutions are suitable for detaching the bearing in an emergency, they prove impractical on factory production lines. Indeed, the gap between the shell and the inner cap makes it very difficult for production operators to engage the notches on the pins. Summary of the invention

[0007] To this end, the invention proposes an assembly of interior padding trim for a helmet, which includes: - a detachable trim element comprising a pad attached to a coupling plate on which is provided at least one coupling section with a notch; and - at least one docking device designed to be mounted on a helmet shell and to cooperate with said notch.

[0008] Furthermore, this at least one mooring element has a general "V" shape and comprises a first wing connected to a second wing by an elastically deformable elbow, in which: - the first wing is equipped with a mounting element to allow the attachment device to be mounted on the helmet shell, - the first wing has an opposing inner and outer face, - the inner face of the first wing faces the second wing and supports a mooring pin that protrudes towards the second wing, and - said mooring pin is dimensioned to cooperate with said notch in order to be able to hook the coupling section onto said mooring pin.

[0009] Thus, the invention proposes to attach the coupling plate to one or more attachment points mounted on the hull, such that each attachment point is interposed (or wedged) between the hull and the inner shell (with the first wing mounted on the hull and the second wing resting on the inner shell). The attachment point is thus compressed to the point that the bend deforms elastically and the second wing moves closer to the first wing. This brings the attachment pin closer to the second wing. On the production line, when the coupling plate is engaged in the gap between the hull and the inner shell, each coupling section is guided by the two wings and between the two wings of the corresponding attachment point, without risk of missing the attachment pin. This solution therefore facilitates the mounting of the detachable trim element, and thus the bearing, onto the hull.

[0010] According to one feature, the second wing has a notch arranged opposite the mooring pin, to allow the mooring pin to be positioned partly inside said notch.

[0011] In this way, when the mooring member is compressed (between the hull and the inner cap), the mooring pin is at least partly in the notch of the second wing, so that when the coupling plate is guided between the two wings, the notch will engage on the mooring pin without risk of missing it.

[0012] According to one possibility, the mounting element is a snap-fit ​​element, male or female, to allow the mounting of the anchoring device by snapping it onto an additional snap-on element, female or male, provided on the helmet shell.

[0013] Thus, the mooring member is mounted by snapping onto the hull, which is advantageous for facilitating its assembly on the production line; it is enough to insert the mooring member into the gap between the hull and the inner shell, for example by means of a suitable tool to push the mooring member, until its snapping element snaps into place on the complementary snapping element.

[0014] According to another possibility, the snap-in element is a male snap-in element which includes a hook which protrudes from the outer face of the first wing.

[0015] The use of such a hook is convenient for the assembler on the production line, as it facilitates snapping onto the complementary snapping element.

[0016] According to another possibility, the hook supports a protruding tooth.

[0017] In a particular embodiment, the second wing has a free termination which ends with a folded edge which is directed in a direction opposite to the first wing.

[0018] This folded edge is designed to pass over the edge of the inner cap and thus facilitate the guidance of the coupling section between the two wings of the mooring member.

[0019] Advantageously, at least one coupling section of the coupling plate comprises several coupling sections, each provided with a notch, and at least one mooring member comprises several mooring members associated with the several coupling sections.

[0020] According to one variant, the detachable trim element is an inner cheek.

[0021] The invention also relates to a helmet comprising: - a shell with an opening delimited by a peripheral edge; - an internal cap located inside the hull; and - at least one set of interior upholstery trim mounted inside the shell.

[0022] This helmet is remarkable in that at least one set of inner padding conforms to the above description, and furthermore: - at least one lashing device is mounted on the shell by means of its mounting element which is mounted on the peripheral edge of the shell, - at least one lashing device is disposed between the shell and the inner liner and is in a compressed configuration with its second wing brought closer to the first wing by elastic deformation at the elbow, - the coupling plate is inserted between the shell and the inner liner so that the notch of at least one coupling section is mounted on the lashing pin of at least one lashing device, so that the padding element detachable is an inner cheek either anchored on at least one mooring device and therefore on the hull.

[0023] In a particular embodiment, the second wing has a notch as previously described, and at least one docking member has its docking pin which is positioned partly inside the notch of the second wing in the compressed configuration.

[0024] According to one possibility, the mounting element is a snap-fit ​​element, male or female, as previously described, and at least one additional snap-fit ​​element, female or male, is provided on the peripheral edge of the helmet to cooperate by snap-fitting with the snap-fit ​​element, male or female, of at least one anchoring member.

[0025] In an advantageous embodiment, the at least one additional snap-on element includes a slot formed in the hull on its peripheral edge, this slot forming the additional snap-on element of the female type, and the snap-on element of the at least one mooring member is male to fit inside said slot.

[0037] [Detailed description of a non-limiting embodiment of the invention]

[0038] With reference to the Figures, the description relates to a set of trim 2 internal padding for a 1 protective helmet, especially for motorcyclists.

[0039] This helmet 1 comprises a rigid shell 3, generally in the shape of an open spherical cap, intended to be worn on the wearer's head and to protect it. The shell 3 is thus provided with an opening at the bottom, delimited by a peripheral edge 30, to allow the user to insert their head inside the helmet 1. This shell 3 has a front part having a frontal opening 31 for the wearer's face, such a front part being able to be equipped with a visor and optionally a chin strap 32, which chin strap 32 may be fixed or movable.

[0040] The helmet 1 further comprises an inner shell 4 disposed inside the outer shell 3. This inner shell 4 is thus positioned between the outer shell 3 and the user's head and is configured to absorb some of the energy received by the helmet 1 in the event of an impact. This inner shell 4 also provides comfort to the user and is advantageously made of an expanded material such as polystyrene or polypropylene.

[0041] In the context of this description, the inner padding assembly 2 is mounted inside the helmet 1, and more specifically inside its shell 3, to form an inner cheek pad, either on the right or left side at the wearer's cheeks. Advantageously, the helmet 1 may also include two such inner padding assemblies 2, one on the right and one on the left.

[0042] The interior upholstery trim assembly 2 includes a detachable trim element 5, visible on its own in [Fig. 10], which includes a pad 56 (also called a detached cushion) attached to a coupling plate 50. This detachable trim element 5 thus forms, in the illustrated example, a detachable inner cheek.

[0043] The pad 56 comprises a flexible cover, made of woven or non-woven material, in which a padding portion, such as foam, is arranged. This pad 56 is thus attached to the coupling plate 50, for example by welding or sewing. The coupling plate 50 is made of plastic or composite material and forms a thin portion designed to be slid / inserted into a gap between the shell 3 and the inner liner 4. This detachable padding element 5 is removable and can be mounted / dismounted from the helmet 1.

[0044] The coupling plate 50 serves to couple or fix the pad 56 to the shell 3 of the helmet 1. As such, the coupling plate 50 has coupling sections 51 provided with respective notches 52. In the illustrated example, the coupling plate 50 has three coupling sections 51, and therefore three notches 52. These notches 52 are provided on an external longitudinal edge 54 of the coupling plate 50, opposite an internal longitudinal edge 55 along which the pad 56 is fixed.

[0045] To ensure this attachment, the inner padding assembly 2 further includes lashing elements 6 intended to be mounted on the shell 3 of the helmet 1 and to cooperate with each of the notches 52 of the coupling plate 50 of the detachable padding element 5; with as many lashing elements 6 as there are notches 52 in the coupling plate 50. Also, in the illustrated example, the inner padding assembly 2 includes three lashing elements 6 for attaching it to the shell 3.

[0046] The lashing members 6 are identical, and each lashing member 6 has a general "V" shape and comprises a first wing 61 connected to a second wing 62 by an elastically deformable elbow 63. The first wing 61 has an inner face 610 facing the second wing 62, and an opposite outer face 611. The second wing 62 has an inner face 620 facing the first wing 61, and an opposite outer face 621.

[0047] Each lashing member 6 is made of a material that allows the elbow 63 to bend, in order to bring the first wing 61 and the second wing 62 closer together or further apart; for example, in a plastic material. Each lashing member 6 can thus be made in one piece.

[0048] The first wing 61 is provided with a hook 64 forming a mounting element configured to allow mounting of the docking device 6 onto the shell 3 of the helmet 1. In the illustrated example, this hook (or mounting element) is configured for mounting the docking device 6 by snapping it onto a slot 34 forming an additional female snap-on element which is provided on shell 3 of helmet 1.

[0049] More specifically, this hook 64 protrudes from the outer face 611 of the first wing 61, and is provided on one end of the first wing 61 opposite the elbow 63. This hook 64 has a "V" shape with a point that supports a projecting tooth 67, designed to anchor the latch in the corresponding slot 34. This slot 34 is formed in the shell 3 on its peripheral edge 30, the hook 64 fitting inside this slot 34, which forms the complementary female latching element. The slot 34 also has an anchoring relief 35 against which the tooth 67 engages, in order to finalize the latching of the hook 64 inside the slot 34.

[0050] Thus, the shell 3 of the helmet 1 has, along its peripheral edge 30, slots 34 on the right and slots 34 on the left which form complementary female snap-fit ​​elements adapted to receive and cooperate with the hooks 64 of the lashing devices 6; with as many slots 34 (or complementary female snap-fit ​​elements) as there are lashing devices 6. Therefore, in the illustrated example, the shell 3 comprises three slots 34 (or complementary female snap-fit ​​elements) on the right and three slots 34 (or complementary female snap-fit ​​elements) on the left. These slots 34 will then be concealed externally by means of a gasket or a trim ring mounted on the peripheral edge 30 of the shell 3.

[0051] On each mooring member 6, the inner face 610 of the first wing 61 supports a mooring pin 65 which protrudes towards the second wing 62, this mooring pin 65 being dimensioned to cooperate with the corresponding notch 52 of the coupling plate 50, in order to be able to hook by interlocking the relevant coupling section 51 onto this mooring pin 65.

[0052] The second wing 62 has a notch 66 arranged opposite the mooring pin 65, to allow the mooring pin 65 to be positioned partly inside this notch 66.

[0053] Each mooring element 6 is thus configurable at least between: - a rest position (visible in Figures 2 to 5), in which the mooring member 6 is not subjected to stress, and in which the mooring pin 65 is outside the notch 66, in other words the free end of the mooring pin 65 is spaced from the second wing 62 and its notch 66; and - a compressed position (visible in Figures 6 to 8), in which the mooring member 6 undergoes compression leading to a relative rapprochement between the first wing 61 and the second wing 62 by elastic deformation at the elbow 63, and in which the mooring pin 65 is positioned partly inside this notch 66; such compression being induced by the inner cap 4 as described below.

[0054] The second wing 62 has a free termination which ends in a folded edge 68 which is directed in a direction opposite to the first wing 61.

[0055] The remainder of the description relates to the mounting of the interior padding trim assembly 2 onto the shell 3 of the helmet 1, as implemented on an industrial assembly line.

[0056] As a preliminary step, the inner cap 4 is mounted inside the shell 3, leaving a gap 8 between the inner cap 4 and the shell 3 at the slots 34.

[0057] Next, each mooring member 6 is slid into the gap 8, for example by means of a tool to push it, until the hook 64 engages inside the slot 34, so that the mooring member 6 is positioned between the hull 3 and the inner cap 4. At the end of this step, the mooring member 6 is mounted and fixed on the peripheral edge 30 of the hull 3, with its two wings 61, 62 which are inside the hull 3 in the gap 8.

[0058] The width of the gap 8 is such that the mooring member 6 is compressed by the inner cap 4 and is therefore in its compressed configuration with its second wing 62 which is brought closer to the first wing 61 by an elastic deformation at the elbow 63; the second wing 62 being pressed against the inner cap 4. Thus, and as can be seen in Figures 6 to 8, the mooring pin 65 is at least partly in the notch 66 of the second wing 62.

[0059] Furthermore, the folded edge 68 of the second wing passes over the edge 40 of the inner cap 4, as seen in Figures 6 to 8, which will facilitate the guidance of the coupling section 51 between the two wings 61, 62 of the docking member 6.

[0060] Next, the coupling plate 50 is also slid into the gap 8, so that each coupling section 51 is opposite the corresponding mooring member 6, until the notch 52 engages with the relevant mooring pin 65. In this step, each coupling section 51 is guided by the two wings 61, 62 and between the two wings 61, 62 of the corresponding mooring member 6, and the notch 52 will engage with the mooring pin 65 without risk of missing it, since there is no gap between the second wing 62 and the free end of the mooring pin 65. Thus, the detachable trim element 5 is anchored to the mooring members 6 and therefore to the hull 3.
