Definitions
- the invention relates to a mounted in the seat back guide in which the guide rod of the headrest is arranged, wherein the guide for height adjustment of the seat headrest is used.
- New regulations for the Whiplash optimized head restraints are forcing manufacturers to use classic head restraints on rear seats that prevent the driver from seeing enough visibility through the rear view mirror, even in unoccupied rear seats, or to use expensive folding head restraints.
- An example of an expensive embodiment of the folding mechanism of the guide rod of the headrest is given in DE4302549C1, where the guide rod is actuated and pivoted via a rack and closable guide jaws.
- the object is achieved by a guide which is arranged in the vehicle seat back and designed for the insertion of the guide rod of the headrest.
- This guide allows the fixation of the headrest in the non-use position, in which it does not prevent the view of the occupants at vehicle rear seats.
- the guide comprises a sleeve, a ring and an unlocking member.
- the sleeve is mounted in the vehicle seat back and has an elongate opening. This opening is formed about the longitudinal axis of the sleeve and adapted for insertion of the guide rod of the headrest.
- the ring of the guide comprises a receptacle and an upper opening which is formed about the longitudinal axis of the sleeve and adapted to the elongate opening of the sleeve.
- the unlocking member of the guide is arranged in the ring of the guide.
- the unlocking member comprises a first locking block, which is arranged in the ring receiver.
- the first locking block of the unlocking member has a first window. Through this first window, the guide rod of the headrest passes in the functional position, i. when the rod is disposed in the elongated opening of the guide sleeve and passes through the upper opening of the ring.
- the illustration of the invention is that on the outside of the guide sleeve, a transverse to its longitudinal axis extending radial opening is formed.
- the ring of the guide comprises an oblique side part which has the holes aligned with the radial opening of the sleeve.
- the radial opening of the sleeve and the perforations of the side part of the ring are formed in the same axis and designed for the insertion of the guide rod of the headrest.
- the unlocking member includes a second locking block having a second window. The second window is formed in the axis of the radial opening of the guide and designed for the insertion of the guide rod of the headrest.
- the guide rod of the headrest is in the non-use position, i. when the rod is disposed in the radial opening of the sleeve of the guide and passes through the perforation of the side part of the ring.
- the guide may further comprise a safety cap which is mounted on the ring of the guide.
- the safety cap points in the axis of the guide sleeve a formed first hole and at its periphery two opposite second holes, which are aligned with the radial opening of the sleeve. Both the first hole and the two second holes are configured for the insertion of the guide rod of the headrest in the guide.
- the guide can be used both for the adjustment of the headrest in the position of use, as well as for fixing the headrest in the non-use position.
- the guides on the front seats the occupants of the rear seats are able to see through the front window of the vehicle.
- the driver is granted maximum visibility through the rear window through the rear window. This solution allows the Whiplash test with classic head restraints with minimal expenses to achieve the highest score.
- Fig. 1 shows an overall view of the stand-alone guide with the cap
- Fig. 2 shows an overall view of the stand-alone guide without cap
- Fig. 3 shows the guide in an exploded view
- Fig. 4 shows an overall view of the headrest in the guide in the position of use
- Fig. 5 shows an overall view of the headrest in the guide in the non-use position.
- Figs. 1 to 3 show a guide 1, which is arranged in the upper region of the vehicle rear seat back.
- This guide 1 is used in Fig. 4 for insertion of the guide rod 3 of the headrest 2 and subsequently to the necessary height adjustment of the headrest 2.
- the guide I comprises a sleeve 4, which is inserted into a part in the seat back and secured there.
- the guide sleeve 4 has an axially elongated opening 8, which is formed around the longitudinal axis of the sleeve 4 and adapted for the insertion of the guide rod 3 of the headrest 2.
- the guide 1 further comprises a ring iL. which is arranged in the upper region of the guide 1, ie in the not inserted in the seat back part.
- the ring 5 of the guide comprises a receptacle 10 and an upper opening 20.
- the upper opening 20 is formed about the longitudinal axis of the sleeve 4 and the elongated opening 8 of the sleeve 4 adapted, in which the guide rod 3 of the headrest. 2 can be inserted.
- the guide 1 further comprises a Entriegeiungsglied 6, in the ring 5 of the guide . 1 is arranged.
- the unlocking member comprises a first Verriegeiungsstein 11, which is arranged in the receptacle 10 of the ring 5.
- the first Verriegeiungsstein 11 of the unlocking member 6 has a first window 12.
- a spring 19 is arranged in the ring, which presses on the back of the locking block H of the unlocking member 6.
- the Verriegeiungsstein H engages due to the pressure of the spring 9 in the individual on the guide rod 3 of the headrest 2 formed locking notches (not shown). Thus, the headrest 2 is locked in the required setting position.
- the ring 5 of the guide comprises an oblique side part 17, which has the aligned with the radial opening 9 of the sleeve 4 perforation 18, as shown in FIGS. 2 and 3 can be seen.
- the radial opening 9 of the sleeve 4 and the perforations 18 on the side part 17 of the ring 5 are formed in the same axis and configured for the insertion of the guide rod 3 of the headrest 2.
- the unlocking member 6 of the guide 1 also includes a second Verriegeiungsstein 13, which has a second window 14.
- the second window 14, formed in the axis of the radial opening 9 of the guide 1, is configured for the insertion of the guide rod 3 of the headrest 2.
- Both the unlocking member 6 with its second Verriegeiungsstein 13, as well as the ring 5 with its side part 18, have some inclination relative to the axis of the sleeve 4. This inclination is adapted to the inclination of the guide rod 3 of the headrest 2, or notch formed on the rod 3 (not shown), so that the second Verriegeiungsstein 13 can engage in this notch.
- the guide 1 further comprises a safety cap 7, which is placed on the ring 5 of the guide.
- the safety cap 7 has in the axis of the sleeve 4 of the guide a trained first hole 15 and the circumference of the safety cap 7 two opposite second holes 16, 16 ', which are aligned with the radial opening 9 of the sleeve 4.
- Both the first hole 15, as well as the two second holes 16, 16 ' are designed for the insertion of the guide rod 3 of the headrest 2 in the guide.
- the rod 3 of the headrest 2 passes through the first window 12 of the first locking stone 11 of the unlocking member 6, ie when the rod 3 in the elongated opening 8 of the sleeve 4 of the guide . 1 arranged and passes through the upper opening 20 of the ring 5.
- the guide has two openings with a double unlocking element.
- the vertical elongated opening 8 is used to adjust the headrest 2 in the use division and the approximately horizontally extending radial opening 9 serves to displace the headrest 2 in the non-use position.
- To secure the headrest 2 in the non-use position is used against the tearing the last one-sided notch (not shown), which is arranged at the end of both guide rods 3 of the headrest 2.
