(14) FIG. 12 shows opening movement of the air purifying device in plan view; and

(15) FIG. 13 shows removal of the filter unit in plan view.

(16) FIG. 1 shows an air purifier 1 that consists of a cover plate 2 as well as of a back plate 5 and an outer circumference 4 that is arranged between the front and rear plate and forms the side surface. A plurality of fins 3 are arranged so as to be distributed on the outer circumference 4 and act as air intake regions or air discharge regions depending on the air passage.

(17) For instance, the intake air can be sucked into the device 1 in the radial direction over a circumferential region extending in the range of from 270-300 degrees, whereas the treated air can be expelled from the device 1 over a circumferential region extending in the range of from 60-90 degrees.

(18) Accordingly, the air discharge region 50 (shown in FIG. 4) extends in an angular range of preferably 60-90 degrees, it being possible for the discharge direction 49 to be changed according to the invention by rotating the device 1 about the rotation axis 40.

(19) The adapter plate 6 has a mounting portion 7, which consists of a coupling sleeve 8 with an opening 9 in the center in which a current-carrying pin that is embodied as a jack plug 10 is placed.

(20) The positioned air purifier 1 can be supplied with the required voltage via this jack plug 10. This is a rotary connection for the power lines that are arranged there, so that the low current that is fed into the adapter plate 6 via the power cable 15 (FIG. 2) is fed into the coupling sleeve 8, in whose central region the bipolar jack plug 10 is arranged, which can be locked into an oppositely situated jack socket that is arranged in the vicinity of a housing-side opening 24. “Low current” is understood to refer to a voltage of 12 volts-24 volts and current of 1-2 amps, for example.

(21) In this way, a complete rotation of the air purifier 1 about the rotation axis 40 in any desired angular range—even multiply about an angle of 360 degrees—in the direction of the arrow 53 is made possible while maintaining the power supply.

(22) For assembly, the air purifier 1 is moved in the direction of the arrow 42 toward the front side 11 of the coupling sleeve 8 and slipped over the coupling sleeve 8, the coupling sleeve being received in the opening 24 of the device. The opening 24 is shown in FIG. 3, for example.

(23) The coupling sleeve 8 has a side region 12 on which at least one locking jaw 13 is placed. When the air purifier 1 is put in place, this locking jaw 13 is first forced into the interior of the coupling sleeve 8 and then engages in the interior of the air purifier 1 in an annular undercut or locking projection 54 in the inner circumference of the opening 24.

(24) In the example that is shown here, the adapter plate 6 consists of the three wings 14a, 14b, 14c, which—bent in the direction of the air purifier—extend in a star shape starting from the coupling sleeve 8.

(25) A power cable 15 can be plugged into the adapter plate 6 via a connector 16 in order to supply the adapter plate 6 with power.

(26) The adapter plate 6 can be connected and fixed to the head restraint bars 18 of a head restraint 19 by means of a belt 17. The air purifier 1 is mobile and can be placed on the adapter plate by hand 20.

(27) FIG. 2 shows only the adapter plate 6 with its three wings 14a, 14b, 14c, which extend in a star shape starting from the coupling sleeve 8. The invention is not limited to this. A number of two or more wings is also to be covered by the present invention.

(28) The coupling sleeve 8 is bell-shaped, so that the air purifier 1 can be placed onto it with its opening 24. The individual wings 14 have rubber-like support pads 43 in their end regions that can engage in an annular opening of the back plate 5 in the vicinity of the outer circumference 4 in order to additionally fix the air purifier 1 in place and prevent inadvertent rotation.

(29) The power cable 15 can be connected to the onboard power supply 22 of the vehicle a commercially available adapter plug.

(30) FIG. 3 shows the individual components of the air purifier 1, which consists of the cover plate 2 and the back plate 5, which have received the filter unit 25 between them. The back plate 5 has an opening 24 into which the coupling sleeve 8 is inserted later. The adapter plate 6 can be connected to the head restraint bars 18 by means of the belt 17. The belt 17 has a buckle 28 for mounting, as will be discussed separately further below. The belt 17 has the ends 27a, 27b, which have already been guided through the buckle 28 in FIG. 3 and are present as free ends.

(31) A discharge chamber 26 into which the fan wheel blows the air on the path toward the air discharge region 50 of the housing during operation is arranged in the portion left open by the filter unit 25.

(32) FIG. 4 shows the housing, in which the intake air 44 is sucked into the interior via the air intake region 45, which is shown in dashed lines, via fins 3 that are arranged radially on the outer circumference.

(33) The intake air 44 is thus sucked into the device 1 in the radial direction in the direction of arrow 46 via a circumferential region that extends in the range of from 270-300 degrees.

(34) The circumferential region for the air intake extends from position 47 to position 48.

(35) The air discharge region 50 thus extends in an angular range of preferably 60-90 degrees from position 48 to position 47.

(36) The air flow that is blown out of the housing-side fins 3 in the vicinity of the air discharge region 50 is thus directed in the direction of the arrow 49.

(37) This discharge flow 51 has such a low air velocity that it is practically unnoticed by the user, so a display light bar 52 is additionally provided in the vicinity of the housing-side fins 3 in order to enable the functioning of the air purifier to be verified.

(38) The contact surface 55 integrated into the cover plate 2 responds to finger pressure. Through actuation thereof, the device can be switched on or the intensity of the discharge flow (51) can be regulated. At least one colored LED (not shown) is integrated into or behind the contact surface 55 in order to alert the user to the current operating state by means of different colors and intensities.

(39) FIG. 5 shows the passage of the belt 17 through the back side of the adapter plate 6. The middle region of the belt 17 is securely connected to the buckle 28.

(40) The belt 17 with its ends 27a and 27b is guided through the lugs 29a, 29b that extend on the rear side on the adapter plate.

(41) The ends 27a, 27b wrap around the head restraint bars as shown in FIG. 6 and are fed back to the buckle 28 through the feedthrough with locking jaws 30a, 30b, where they are guided through corresponding openings and pulled tight in the direction of the arrow 32 and opposite to the direction of the arrow 32 in order to thus secure the adapter plate to the head restraint 19.

(42) FIG. 7 shows an alternative mounting variant for the adapter plate 6, which can be mounted on the seat surface 37 in the example shown here. The adapter plate 6 is secured for this purpose by means of the belt 33, which is guided by a strap 34 of the adapter plate 6.

(43) FIG. 8 shows how the belt 33 is inserted into the clasp 35 and the power plug 15 is connected to the on-board power supply 22.

(44) The air filter device 1 can then be set in place on the adapter plate 6 in the direction of the arrow 36, as shown in FIG. 9, with the device connecting to the coupling sleeve 8, and with the power supply of the air filter device 1 also being ensured by the power connection that is routed through the coupling sleeve.

(45) FIG. 10 shows how the air purifier 1 according to the invention can be removed from the head restraint 19. For this purpose, a release button 38 that is present on the adapter plate 6 can be actuated, whereby the locking jaws 13 are disengaged from the opening 34 of the air purifier 1 and the air purifier 1 can thus be removed from the head restraint 19 in the direction of the arrow 39.

(46) As is shown in FIG. 1, the release button 38 can be mounted on the side of the adapter plate 6, or also on the back of the adapter plate (not shown), from where it can be easily operated.

(47) FIG. 11 shows how, after the removal of the air purifier 1, the adapter plate 6 now remains on the back of the seat or the head restraint 19.

(48) FIG. 12 shows how the air purifier 1 can be opened during rotation of the cover plate 2 in the direction of the arrow 41 about the axis 40.

(49) According to FIG. 13, after the cover plate 2 is opened, the filter unit 25 can be removed from the interior of the air purifier 1 by hand 20.
