Description
Automobile seat having automatically or optionally height-adjustable head rest
The invention refers to an automobile seat with automatically height adjustable head rest. According to the International Patent Classification, such invention belongs to vehicles, namely to passenger accomodation and seats adapted for passengers, in particular to seats or corresponding head rests which are constructed to protect occupants from the effect of abnormal forces.
The purpose of the invention is to create a seat with a height-adjustable head rest, wherein the head rest should be on the one hand automatically adjustable depending on each position and each displacement of the seat in the horizontal direction, and on the other hand, each user should also be able to amend or correct manually said automatically adjusted position of the height-adjustable head rest, by which however each additional displacement of the head rest would have to be unambiguously identified from outside.
An automobile seat with automatically self-adjustable head rest is disclosed in JP 2004-352165. Such seat comprises a frame, namely a seat frame with a rail assembly and a rest frame together with a head rest. Said rail assembly is fixed to the vehicle body in the passenger area and is adapted to support and also to guide said seat frame, to which said rest frame is pivotally attached. The seat frame is displaceable along said rail assembly and can be also irrespective to position of the seat frame relative to the seat frame fixed in each desired position. A head rest is mounted in the top end portion of the rest frame, and is inserted within appropriate guides, by which it is then height-adjustable. In order to enable automatically height-adjusting of the head rest in dependency on each position of the seat frame, the head rest is furnished with a driving unit, which is via appropriate transmission means connected with the seat frame and the rail assembly. Consequently, each longitudinal displacement of the seat frame relative to said rail assembly results in appropriate height-displacement of the head rest, wherein the correlation between each displacement of the head rest and each longitudinal displacement of the seat frame is simply linear. As a matter of fact, a rack is mounted on said rail assembly for the purposes of cooperating with a gear, which is either directly or indirectly via corresponding shaft connected with a winding element for winding a cable, e.g. with a pulley or a drum, while the other free end portion of said rope is wound on the winding element in the area of the rest frame or the head rest, respectively. The lastly mentioned winding element is connected with a spindle, which cooperates with a nut, which is mounted in the head rest. In order to maintain the head rest in each desired position at a desired level obtained by turning said spindle, the pitch of the thread is relatively small and the spindle is a self-stopping one.
The purpose of such head rest is essentially to assure a sufficient support for a head of the passenger and to prevent the head from injuries in the case of unexpected rearward impact in the case of a rearward crash, wherein the efficiency
of such protection merely depends on correct position of the head rest with respect to its altitude, and also on the distance between the head rest and the back of the passenger's head. Whenever the head rest is located too high or too low, or the distance between the head rest and the back of the passenger's head is too long, such protection may be completely inefficient.
Said solution pursuant to JP 2004-352165 generally enables automatically increasing the altitude of the head rest when e.g. a driver or a passenger with larger body height would move the seat correspondingly rearwards. On the contrary, by displacing the seat forwards, the head rest is correspondingly dropped. However, each displacement is performed in accordance with a previously mentioned linear correlation between each desired position of the seat frame and the head rest, wherein each possible displacement is also pretty limited due to said small pitch of the thread on the spindle due to achieving said self-stopping effect.
Each seat is generally available for users with various anthropologic properties or ergonomic requirements, which are by means of appropriate longitudinal displacement of the seat allowed to determine each appropriate distance between the seat and pedals and/or s steering wheel. When considering the previously exposed limitations in adjusting the head rest in the vertical direction, it is obvious that despite to regular adjustment of the seat frame in the longitudinal direction, when considering various anthropological conditions e.g. in various geographic regions, each obtained position of the head rest can easily be inappropriate, either too high or too low, which is the context of potentially providing a support for the head in the case of rearward impact insufficient per se, and which moreover also results in gaining correspondingly longer distance between the head rest and the back of the head, which among others leads to increasing the risk of injuries due to accelerations i.e. the forces, which may occur by rearward impacts e.g. by crash.
An automobile seat with automatically height-adjustable head rest is moreover disclosed in the currently still unpublished Slovenian patent application No Si.P- 201100017. Such seat comprising a seat frame, a rest frame, a guiding assembly and a head rest. Said guiding assembly is formed by two longitudinally with respect to the vehicle extending guides, which are fixed to a vehicle body or any other part of the vehicle in the area of mounting each seat. Said seat frame comprises at least a pair of lateral beams, which extend longitudinally with respect to each vehicle and are spaced apart from each other and firmly interconnected with each other by means of transversal spacers, wherein said seat frame is embedded within said guides of the guiding assembly with the possibility of being displaced along said guides and blocking thereof in each desired position. Said rest frame preferably comprises at least a pair of lateral beams, which extend longitudinally with respect to the vehicle and are spaced apart from each other and firmly interconnected by means of transversal spacers, and is on its end portion apart from the seat frame furnished with guiding bushes, which are parallel to each other and at least approximately to said lateral beams, and are moreover adapted to receive a head rest, wherein said seat frame is pivotally attached to the seat frame such that the rest frame can be pivoted relative to the seat frame and fixed in each desired position. Said head rest comprises a body, which is inserted through said bushes on the rest frame, as well as at least one longitudinal beam, which is intended for displacing the head rest along said bushes and relative to the rest frame. Said transmission assembly comprises at least one flexible transmission element suitable for transferring longitudinal displacements of the seat frame relative to each belonging guide towards the area of the longitudinal beam for the purposes of displacing the body of the head rest along said bushes (24', 24") and relative to the rest frame.
Said transmission assembly is conceived in such a manner that each forward or rearward displacement of the seat frame relative to each belonging guide of the guiding assembly is transferred into the area, in which the head rest is embedded on the rest frame, via corresponding transmission elements, namely via at least one flexible transmission element and at least one compensation assembly and/or at least one transmission ratio transforming element, which is adapted to function either as a reducing or multiplying means, wherein each displacement of said seat frame relative to the guide is simultaneously followed with appropriate displacement of the head rest relative to the rest frame, the length of which and/or time dependency is different than by said displacement of the seat frame relative to the guide. The base of the head rest is displaceable along at least one guiding bush and relative to the rest frame either in a step-like manner or continuously. Consequently, displacing of the head rest in the sense of height-adjusting is performed automatically, although the ratio between the vertical displacement of the head rest and the horizontal displacement of the seat can also be predetermined. For a statistic majority of users, such automatic adjustment of position of the head rest relative to each desired position of the seat can be optimally determined. However, there is always certain population, for which such automatically adjusted position of the head rest needs to be temporarily or permanently modified.
The present invention refers to an automobile seat with automatically or optionally height-adjustable head rest, wherein such seat comprises a seat frame, a rest frame, a guiding assembly, a head rest and a transmission assembly, and wherein
- said guiding assembly is formed by at least two guiding rails, which extend in a longitudinal direction of each vehicle and are attached to a vehicle body or any other part of the vehicle in the area of mounting the seat;
- said seat frame preferably consists of a at least a pair of lateral bearing members, which are spaced apart from each other and extend in a longitudinal direction of each vehicle and are moreover firmly connected with each other by means of transversal spacers, wherein said seat frame is embedded within said guiding rails of the guiding assembly and is allowed to be displaced along said guiding rails with the possibility of being fixed in each desired position;
- said rest frame preferably consists of at least a pair of lateral bearing members, which are spaced apart from each other and extend in a longitudinal direction of each vehicle and are moreover firmly connected with each other by means of transversal spacers, wherein the rest frame is furnished with two guiding bushes, which are located on the end portion of the rest portion apart from the seat frame and extend at least essentially parallel to said lateral bearing members and are moreover adapted to receive the head rest, and wherein said rest frame is pivotally interconnected with the seat frame in order to be pivoted relative to said seat frame with the possibility of being fixed in each desired position;
- said head rest in addition to each desired upholstery comprises at least two bearing members, which extend parallel to each other and are insertable into said guiding bushes on the rest frame, as well as at least one longitudinal beam which is suitable for displacing the head rest relative to the rest frame along said guiding bushes; while
- said transmission assembly comprises at least one flexible transmission member, which is adapted to transfer longitudinal displacements of the seat frame relative to each belonging guiding rail of the guiding assembly towards the area of said longitudinal beam for the purposes of displacing the bearing members of the head rest within the bushes relative to the rest frame;
and wherein said transmission assembly is conceived in such manner that each displacement of the seat frame in a forward or rearward direction relative to each belonging guiding rail of the guiding assembly is by means of each disposable
flexible transmission member and at least one compensating assembly and/or at least one transmission ratio changing member, functioning either as transmission ratio reducing or multiplying member, transferred towards the area of placement of the head rest onto the rest frame, so that each displacement of the seat frame relative to each belonging guiding rail is followed by synchronous displacement of the head rest relative to the rest frame, by which the length and/or timing of the lastly mentioned displacement preferably differs from the previously mentioned displacement of the seat frame.
In accordance with the invention, the seat further comprises a control assembly, which is located in the area of the head rest and essentially consists of a casing, which is at least partially surrounded with the upholstery of the head rest and adapted to receive at least one control button and at least one indicating button, wherein the control button is inserted and elastically supported within said casing and is adapted both for establishing each required engagement between the head rest and at least one bearing member and optionally also for interrupting said engagement in order to enable temporarily displacing of the head rest relative to the said bearing members, namely along said bearing members,
and wherein the indicating button is inserted within said casing and is adapted to cooperate with a notch, which is foreseen on the surface of at least that bearing member of the head rest, which is adapted to cooperate with the control button, so that each displacement of the head rest relative to the previously mentioned notch is visible from outside on the basis of essentially changed position of the indicating button.
In a preferred embodiment of the invention, said indicating button is on the one hand by means of a tension spring connected with the casing and is on the other hand via corresponding levers rest on the surface of the bearing member of the
head rest, wherein the first end portion of said spring is attached to the casing, whilst the second end portion of said spring is attached to the indicating button.
In such case the indicating button is pivotally connected with the first lever, the third lever is adapted either to be engaged within the notch or to be rest on the external surface of the bearing member, while the second lever is on the one hand pivotally connected to the first lever and on the other hand also pivotally to the third lever and is moreover capable to enlarge displacements of the third lever in order to achieve larger displacements of the first lever and the indication button.

Automobile seat with automatically or optionally height-adjustable head rest 4 consists of a seat frame 1, a rest frame 2, a guiding assembly 3, a head rest 4, a
transmission assembly and a control assembly 6, which is according to the invention arranged on said head rest 4 (Fig. 1).
Said guiding assembly 3 is formed by two guiding rails 31, which extend in longitudinal direction of the vehicle and are mounted to a vehicle body or any other part thereof in the area of mounting the seat.
In the shown embodiment, the seat frame 1 consists of a pair of lateral bearing members 11, which are spaced apart from each other and extend in longitudinal direction of the vehicle, and which are firmly connected to each other by means of transversal spacers 12, wherein said frame 1 is embedded within said guiding rails 31 of the guiding assembly 3 and is displaceable along said rails 31 with the possibility of blocking in each desired position.
Said rest frame 2 is formed of a pair of lateral bearing members 21, which are spaced apart from each other and extend in longitudinal direction of the vehicle and are firmly connected with each other, e.g. by means of not-shown transversal spacers, and is moreover furnished with a pair of guiding bushes 24', 24", which and are located on the end portion of the rest frame 2 apart from the seat frame 1 and extend essentially parallel to said lateral bearing members 21, and are moreover adapted to receive a head rest 4. The rest frame 2 is pivotally connected with the seat frame 2, so that the rest frame 2 can be pivoted relative to the seat frame 1 and fixed in each desired position.
The head rest 4 consists of a pair of bearing members 40', 40", which are inserted within said guiding bushes 24', 24" on the rest frame 2, as well as of a longitudinal beam 41 , which is adapted for displacing the head rest 4 relative to the rest frame 2 along the guiding bushes 24', 24". In the shown embodiment, said
bearing members 40', 40" are formed of round tubes and furnished with chrome- plated external surfaces, and are moreover furnished with grooves 44 for enabling step-like displacing of the head rest 4 (Fig. 7).
The transmission assembly 5 comprises at least one flexible transmission member 51, 52, which is suitable for transmission of longitudinal movements of the seat frame 1 relative to each belonging guiding rail 31 of the guiding assembly towards the area of the longitudinal beam 41 for the purposes of displacing the bearing members 40', 40" of the head rest 4 within the bushes 24', 24" relative to the rest frame 2. In the shown embodiment, two flexible transmission members 51, 52 are foreseen. Said transmission assembly 5 is conceived in such manner that each displacement of the seat frame 1 in the forward or rearward direction relative to each belonging guiding rail 31 of the guiding assembly 3 is via at least one transmission member 51, 52 and preferably also via at least one supplemental transmission member suitable either for increasing or decreasing of the transmission ratio of displacements similar like in aforementioned solution according to SI-P-201100017 transferred into the area of mounting the head rest 4 onto the rest frame 2, so that each movement of said seat frame 1 relative to the guiding rail 31 is synchronously followed by adequate movement of the head rest 4 relative to the rest frame 2, wherein the length and/or timing of said movement preferably differs from the length and/or timing of said movement of the seat frame 1 relative to the guide 31.
As shown in Fig. 2, a control assembly 6 is foreseen on the head rest 4, and is embedded within a corresponding casing 60, which is surrounded by appropriate upholstery 43 of the head rest 4. The control assembly comprises at least one control button 61 and at least one indicating button 62, which are each per se embedded within said casing 60.
As already mentioned, the head rest 4 is thanks to bearing members 40', 40" displaceable along the guiding bushes 24', 24" of the rest frame 2 and consequently relative to said rest frame 2. Thanks to said control assembly 6, namely to engagement of the control button 61 and the grooves 44 on at least one of said bearing members 40', 40", the head rest 4 is optionally displaceable along said bearing members 40', 40". By pressing said button 61 against the force of a not shown spring, the engagement between the head rest 4 and at least one bearing member 40', is temporarily eliminated, while on the contrary said head rest 4 is all the time freely displaceable along the other bearing member 40". Upon the button 61 has been pressed, the head rest 4 can be freely displaced at each desired length along said bearing members 40', 40" and therefore relative to said bearing members 40', 40" and also relative to the rest frame 2, by which each position of the head rest 4, which has been prior to that automatically set, can be manually amended and adapted to each particular user. As soon as the pressure towards the control button 61 is eliminated, the engagement between the head rest 4 and at least one bearing member 40', 40" is re-established, upon which the head rest 4 can be displaced exclusively on the basis of displacement of the seat frame 1 relative to the guiding assembly 3.
However, a possibility must be given to identify, whether such additional displacement of the head rest 4 relative to the bearing members 40', 40" has been performed or not. Otherwise, automatically adjusting of position of the head rest 4 could be started from the false origin. To this aim, at least one indicating button 62 is foreseen on the head rest 4, in particular within the casing 60, and is intended to cooperate with a transversal notch 45 on that bearing member 40', which cooperates with the control button 61.
Said transversal notch 45 can be V-shaped in its profile. Moreover, at least a part of the external surface of said indicating button 62 can be visually annotated, e.g. red colored.
Said indicating button 62 is inserted within the casing 60 and is on the one hand tensioned towards the casing 60 by means of a tension spring 66, the first end portion of which is attached to the button 62 and the second end portion to the casing 60. On the other hand, said indicating button 62 is via levers 621, 622, 623 rest on the surface of each belonging bearing member 40' of the head rest 4. The first lever 621 is adapted to cooperate with the indicating button 62 and is pivotally connected therewith. The third lever 623 is adapted to cooperate with the bearing member 40' and can be either inserted into said transversal notch 45 on the bearing member 40', or can be simply rest on the external surface of the bearing member 40'. The second lever 622 is on the one hand pivotally connected to the first lever 621 and on the other hand also pivotally with the third lever 623, by which it engaged both with the first and the third lever 621, 622 and is functioning as multiplier of displacements, so that even relatively short displacement of the third lever 623 from said notch 45 towards the external surface of the bearing member 40', or vice versa, is then expressed by essentially longer displacement of the first lever 621 and consequently essentially longer displacement of the indicating button 62 in a direction outside from said casing 60, by which also the identification of any re-arrangement of the head rest 4 is essentially more efficient.
In the original position of the head rest 4, namely when automatically adjusted with respect to each particular position of the seat frame 1 relative to the guiding assembly 3, the third lever 623 of the indicating button 62 is in engagement with the notch 45 on the surface of the bearing member 40', while the indicating button 62 itself is placed within the casing 60. By a subsequent displacement of the head
rest 4 by means of pressing the control button 61 the head rest 4 is moved along the bearing members 40', 40", wherein the third lever 623 of the indicating button 62 is removed from said notch 45 on the surface of the bearing member 40' and is then rest on the surface of said bearing member 40' itself, wherein the displacement of the third lever 623 is via the second lever 622 transferred to the first lever 621, which is displaced in essentially greater extent, by which the indicating button 62 is moved outside of the casing 60 against the force of said spring 66.
Returning the head rest 4 into its original position and enabling further automatically adjusting of position of the head rest 4 is performed by pressing the control button 61 and displacing the head rest 4 along the bearing members 40', 40" until the third lever 623 is returned into the notch 45 and the indicating button 62 is thanks to the spring 66 returned back into the casing 60.
