Description

The present invention relates to a device

  sun visor for motor vehicles, in parti-

  for commercial vehicles, in which the

  sun visor is arranged in the longitudinal lateral zone

  of the driver's cab and can rotate

  turn of a substantially horizontal axis which is now

naked by at least one offset bearing.

  In known solutions of this type for

  sun visors arranged in the long lateral zone

  of the driving cab, these

  only move around the pivot axis.

  substantially horizontal, and is therefore not

  it is not possible, particularly when recep-

  in the front wall area of the driver's cab above the windshield, to provide lateral protection in which a direct continuity between the associated or windshield sunshades and those arranged in the longitudinal lateral zone is assured. The consequence is that annoying solar radiation can not be effectively prevented in the anterior corner area

by the sun visors.

  The present invention therefore

  purpose of making a sunshade device

  also putting protection in the

  corner, contiguous to the windshield.

  According to the invention, this is, in the case of a sunshade device of the type indicated

  in the preamble, obtained by the fact that

  the eye is slidably guided by means of the offset bearing on a guide rail substantially

  parallel to the pivot axis. It is thus in

  first place to provide, for the sun visor, a raised rest position, in which it is

  sufficiently offset towards the rear vis-à-vis the

  breeze, in order to be outside the mostly flat roof-to-windshield area or behind planned roof receptacles

  adjacent to the windshield. In addition, thanks to the separation

  between the longitudinal mobility and the pivoting, that is to say by the separation of the pivot axis of the guide rail, it is possible for the pivot axis to take a position in which mutual genes between the sunshade device and curtain devices possibly provided and the like are avoided. The guide rail can indeed be moved upwards against the

  roof, without altering the functional position

  the pivot axis, while simultaneously

  the pivot axis, because of its guidance by at least one offset bearing, can be placed from the

  most advantageous way taking into account the

  sun visor. In particular, thanks to the

  figuration of the offset bearing or bearings, it is also possible that a possible curtain rail guide can be arranged extending substantially between the guide rail and the pivot axis, so that in particular in the case where the sun visor is folded

  inactive position, it also forms a mass

  quage for guiding curtains as well as for

the guide rail itself.

  In the embodiment of the invention, it turns out

  it is advantageous to provide as a guide rail a sectional C-shaped profile, open towards the viewing side, which allows on the one hand a particularly simple mounting, and on the other hand a particularly stable guide and

sure for the offset bearing.

  A particularly advantageous achievement

  lies in the fact that the level or levels

  the sunshade is or are disposed substantially in the longitudinal central region of the sun visor, so that with respect to the effective extent of the guide rail in

  the longitudinal direction of the latter, an overlap

  The sunshade can then be moved in a desired manner almost against the windshield when the guide rail as such can not continue as well. away against the windshield.

  In a particular embodiment

  advantage of the invention, the sun visor is guided by means of two offset bearings of which

  the arms facing down are equipped with two

  voting in opposite directions, which

  in receiving bores extending in opposite directions from a longitudinal median housing provided in the upper marginal area

sun visor.

  The invention is explained below in detail with the help of an exemplary embodiment, with regard to the

attached drawings.

  Figure 1 is a schematic representation of

  that in perspective of a part of a cabin of con-

  truck pick, equipped with a bumper

  leil according to the invention, the sun visor being rotated

  in its inactive or rest position.

  FIG. 2 is a representation similar to FIG. 1, in which the windshield is pivoted

in its active position.

  Figure 3 is a schematic section of a guide rail, wherein the visor is guided longitudinally through its offset bearings and has a C-shaped profile in section.

  The driver's cab, shown schematically

  partially, is designated by reference numeral 1 in the figures. At the front, the driver's cab is equipped with the windshield, which, which is not visible here, is usually arranged above a deck not shown here and extends to the roof area. . Laterally contiguous to the windshield 2, is represented the window pillar 3 forming the corner delimitation of the cabin and

  to which door 4 of the cabin is attached, which is

  1 of the front baffle 5 and the other door window 6. In the roof space 7 bent upwards from the cabin 1, is disposed frontally, in the area above the windshield 2, a receptacle 8, which is configured in a manner not shown in detail and on the underside of which are arranged sunshades 9 foldable in front of the windshield. These

  sunshade 9 can pivot about axes

  in the transverse direction of the cab, of their

  rest position according to Figure 1 in their posi-

  active participation according to Figure 2. In this position

  they cover the upper

windscreen 2.

  Laterally above door 4 of the

  cabin, is arranged in the longitudinal lateral zone

  The roof of the vaulted roof curved upwards, thus on the longitudinal side wall of the roof, a guide rail 10 which extends substantially horizontally in the longitudinal direction of the cabin and which has a section, as shown in particular in FIG. FIG. 3, a C-shaped section, open towards the

  side of vision. In this guide rail 10, are

  sliding two offset bearings 11, which

  pivoting the sun visor 12 arranged laterally

longitudinally.

  The sun visor 12 is placed on the staggered bearings by means of two pivots, which are

  find themselves aligned with each other and determine

  the pivot axis parallel to the guide rail of the sun visor 12. Preferably, the pivots are secured to the offset bearings 11 and extend, with reference to the mounting position shown, in

  opposite directions, so that they penetrate

  trent in receiving bores of the sunshade.

  These bores start from the lateral limits of a box

  13 disposed in the longitudinal central region of the sun visor 12, housing in which the offset portions 11 penetrate by their arms 14 carrying the pivots, the depth of penetration of the arms 14

  bearings, approximately corresponding to the

  melter of the housing 13, being determined substantially

  by sizing the pivots. Decades

  11, in the mounted state of the sun visor 12, are

  their mutual spacing, so that they

  can be moved over the joint sun visor 12

  in the guide rail. 10. Because the

  11 between them is appreciably less

  The length of the sun visor results for a relatively short guide rail 10, a relatively long travel distance which, in combination with the approximately median arrangement of the bearings 11 relative to the sun visor 12, also makes it possible to shifting the hood longitudinally forwardly to near the windshield 2, without the guide rail 10 itself having to penetrate into

  in this area. On the contrary, it can be

  outside the pivot area of

  9 associated with the windshield 2, so that

  they can be made to a maximum width and thus provide protection over the entire width

  from the windshield 2. To these front sun visors 9, the

  sun 12 disposed laterally longitudinally in

  its active position, as can be seen from the

  Figure 2, can follow directly and possibly even overlap, so that a whole protection is also provided to the side. There is no obstacle to the mobility of the sun visor 12 because

  of the receptacle 8, when the sun visor 12 is moved

  in its active position, folded down

against the sun visor 2.

  Similarly, the sun visor 12

  can also be placed in the opposite direction

  away, so that as appropriate, appropriate protection can be ensured

  against a lateral radiation from the back. In by-

  particular, in this position, the sun visor 12 can also be used, for example in the case where the window is slightly open, so as to avoid

direct lateral suction.

  Due to the separation of the guide rail 10 and the pivot axis 15 of the sun visor 12, which is determined by the pivots, it is possible to simply provide the sun visor in addition to a curtain device in which the curtain runs

  in a rail 17 extending laterally longitudinally

  LEMENT. With regard to this curtain rail 17,

  adopts, according to the invention, the provision according to

  the guide rail 10 extends above the curtain rail and wherein the offset bearings 11 cover with their arms 14 projecting this curtain rail. In addition, the height offset of the guide rail 10 relative to the position of the pivot axis 15 determined by the offset bearings 11

  has the consequence that, during the pivoting of the

  sun 12 in the inactive position, that is to say

  upwards, this covers at least for the essen-

  the guide rail 10, so that it is removed from view and the mechanism necessary for the longitudinal displacement of the visor 12 does not spoil the overall appearance.
