Description

НАЗВАНИЕ ИЗОБРЕТЕНИЯ: МЕХАНИЗМ РЕГУЛИРОВКИ УГЛА НАКЛОНА  TITLE OF THE INVENTION: TILT ANGLE ADJUSTMENT MECHANISM
СПИНКИ СИДЕНЬЯ  SEAT BACK
ОБЛАСТЬ ТЕХНИКИ FIELD OF TECHNOLOGY
Изобретение относится к устройству сиденья, преимущественно к устройству сиденья транспортного средства с трансформируемым салоном, и используется для регулировки угла наклона спинки сиденья.  The invention relates to a seat device, mainly to a seat device of a vehicle with a convertible interior, and is used to adjust the angle of the seatback.
ПРЕДШЕСТВУЮЩИЙ УРОВЕНЬ ТЕХНИКИ  BACKGROUND OF THE INVENTION
Предлагаемое изобретение преимущественно предназначено для сидений таких транспортных средств, где возможна трансформация внутреннего пространства салона за счет смещения сиденья или группы сидений (дивана) по направляющим, расположенным в полу салона транспортного средства. В таких транспортных средствах крепление пассажирских ремней безопасности всеми концами осуществляется к сиденью, чтобы было возможно перемещать сиденье по салону в некотором диапазоне. Для таких передвижных сидений предъявляются более высокие требования к надежности соединения основания и спинки сиденья, поскольку в момент критических ситуаций большая часть нагрузки ложится именно на их соединение. По этой причине применяемый для таких сидений механизм регулировки угла наклона спинки сиденья должен обеспечивать максимально высокую надежность фиксации основания и спинки сиденья при любом угловом положении.  The present invention is mainly intended for the seats of such vehicles, where the interior of the cabin can be transformed by shifting the seat or group of seats (sofa) along the guides located in the floor of the passenger compartment of the vehicle. In such vehicles, the passenger seat belts are attached at all ends to the seat so that it is possible to move the seat around the cabin in a certain range. For such mobile seats, higher demands are placed on the reliability of the connection between the base and the back of the seat, since at the time of critical situations most of the load falls on their connection. For this reason, the mechanism for adjusting the angle of inclination of the seatback used for such seats should provide the highest possible reliability of fixing the base and backrest for any angular position.
Известен механизм регулировки угла наклона спинки сиденья транспортного средства, патент US6827403, МПК B60N2/235, опубл. 04.11.2004, который принимаем за прототип. Механизм расположен с одной боковой стороны сиденья и обеспечивает регулировку наклона спинки сиденья в пределах небольшого угла в 15 градусов. Известный механизм включает элемент спинки сиденья с дугой зубьев, шарнирно закрепленную на основании сиденья запирающую планку с ответной дугой зубьев и фасонным отверстием, толкатель запирающей планки, выполненный в виде фасонного кулачка, который шарнирно закреплен на основании сиденья и расположен внутри фасонного отверстия запирающей планки. Контур фасонного отверстия состоит из нескольких изогнутых поверхностей и обеспечивает два предельных угловых положения кулачка-толкателя. Фасонный кулачок жестко соединен с рычагом, при воздействии на который сидящий на сиденье человек приводит в действие указанный механизм. Для регулировки угла наклона спинки человек, сидящий на сиденье, воздействует на рычаг, который поворачивает кулачок по часовой стрелке вокруг его оси. При вращении кулачок упирается в рабочую поверхность фасонного отверстия и «толкает» запирающую планку, при этом ее зубья выходят из контакта с ответными зубьями элемента спинки сиденья. Далее воздействуют на спинку сиденья и выбирают нужный угол наклона. Для фиксации угла наклона спинки поворачивают кулачок против часовой стрелки вокруг его оси, он упирается в другую рабочую поверхность фасонного отверстия и поворачивает запирающую планку, при этом ее зубья входят в захват с зубьями элемента спинки, что обеспечивает угловую фиксацию спинки сиденья. В момент критических ситуаций при больших нагрузках элемент спинки с дугой зубьев с большой силой воздействует на запирающую планку. Поскольку толкатель контактирует только с малой частью поверхности фасонного отверстия запирающей планки, то в результате такого воздействия может произойти деформация фасонного отверстия или может произойти самопроизвольный поворот кулачка из положения, обеспечивающего сцепление зубьев элемента спинки и прижимной планки. Таким образом, основным недостатком известного устройства является недостаточная надежность угловой фиксации спинки сиденья относительно его основания при больших нагрузках. Другим недостатком известного механизма является технологическая сложность изготовления фасонной формы кулачка и отверстия запирающей планки, которые имеют сложную геометрическую форму. The known mechanism for adjusting the angle of the seatback of a vehicle seat, patent US6827403, IPC B60N2 / 235, publ. November 4, 2004, which we take as a prototype. The mechanism is located on one side of the seat and provides adjustment of the tilt of the seatback within a small angle of 15 degrees. The known mechanism includes a seat back element with an arch of teeth, a locking bar pivotally mounted on the base of the seat with a reciprocal arch of teeth and a shaped hole, a pusher of the locking bar made in the form of a shaped cam that is pivotally mounted on the base of the seat and is located inside the shaped hole of the locking bar. The contour of the shaped hole consists of several curved surfaces and provides two limit angular positions of the cam follower. The shaped cam is rigidly connected to the lever, when exposed to which the person sitting on the seat actuates the specified mechanism. To adjust the angle of the backrest, the person sitting on the seat acts on a lever that rotates the cam clockwise around its axis. During rotation, the cam abuts against the working surface shaped holes and “pushes” the locking bar, while its teeth come out of contact with the reciprocal teeth of the seat back element. Next, act on the back of the seat and select the desired angle. To fix the angle of the backrest, the cam is turned counterclockwise around its axis, it abuts against the other working surface of the shaped hole and rotates the locking bar, while its teeth enter the grip with the teeth of the backrest element, which ensures angular fixation of the seatback. At the time of critical situations with high loads, the backrest element with the arc of teeth acts with great force on the locking bar. Since the pusher is in contact only with a small part of the surface of the shaped hole of the locking bar, as a result of such an impact, the shaped hole may deform or the cam may spontaneously rotate from the position that provides adhesion of the teeth of the back element and the pressure bar. Thus, the main disadvantage of the known device is the lack of reliability of the angular fixation of the seatback relative to its base under heavy loads. Another disadvantage of the known mechanism is the technological complexity of manufacturing the shaped cam and the holes of the locking bar, which have a complex geometric shape.
РАСКРЫТИЕ ИЗОБРЕТЕНИЯ SUMMARY OF THE INVENTION
Технический результат направлен на повышение надежности угловой фиксации спинки сиденья относительно его основания и упрощение технологического процесса изготовления механизма.  The technical result is aimed at improving the reliability of the angular fixation of the seatback relative to its base and simplifying the manufacturing process of the mechanism.
Технический результат достигается тем, что предложен механизм регулировки угла наклона спинки сиденья, содержащий расположенный с боковой стороны сиденья несущий корпус, жестко соединенный с основанием сиденья, на котором расположены оси шарнирно закрепленных элементов механизма, в частности элемента спинки сиденья с дугой зубьев, запирающей планки с дугой ответных зубьев и отверстием, толкателя запирающей планки, расположенного внутри ее отверстия, при воздействии на который происходит зацепление/расцепление зубьев запирающей планки и зубьев элемента спинки сиденья, при этом толкатель выполнен в виде круглого эксцентрика, отверстие запирающей планки имеет круг дую форму того же диаметра, а запирающая планка шарнирно закреплена на оси с зазором. The technical result is achieved by the fact that the proposed mechanism for adjusting the angle of inclination of the back of the seat, comprising a bearing housing located on the side of the seat, rigidly connected to the base of the seat, on which are located the axis of the pivotally mounted elements of the mechanism, in particular of the backrest element with an arc of teeth, a locking bar with an arch of reciprocal teeth and a hole, a pusher of a locking bar located inside its hole, when exposed to which the teeth engage / disengage the locking plan ki and teeth of the backrest element, the pusher is made in the form of a circular eccentric, the opening of the locking bar has a circular shape of the same diameter, and the locking bar is pivotally mounted on the axis with a gap.
Предложенное устройство поясняется следующим графическим материалом.  The proposed device is illustrated by the following graphic material.
На фиг. 1-3 изображен механизм регулировки угла наклона спинки сиденья в определенные моменты его работы. На фиг. 1 показан момент, когда запирающая планка находится в первом предельном положении, и при котором зубья запирающей планки и зубья элемента спинки сиденья находятся в полном зацеплении. На фиг. 2 показан момент, когда запирающая планка находится в промежуточном положении, при котором указанные зубья частично вышли из зацепления. На фиг. 3 показан момент, когда запирающая планка находится во втором предельном положении, при котором указанные зубья полностью вышли из зацепления. In FIG. 1-3 shows a mechanism for adjusting the angle of inclination of the seatback at certain points of its operation. In FIG. 1 shows the moment when the locking bar is in the first limit position, and in which the teeth of the locking bar and the teeth of the seatback element are fully engaged. In FIG. 2 shows the moment when the locking bar is in an intermediate position in which said teeth are partially out of engagement. In FIG. Figure 3 shows the moment when the locking bar is in the second limit position at which said teeth are completely out of engagement.
Указанный механизм содержит несущий корпус 1, жестко соединенный с основанием сиденья 2 и расположенный с одной боковой стороны сиденья. На несущем корпусе 1 расположены три оси шарнирно закрепленных элементов механизма. Первая ось 3 является осью элемента спинки сиденья 4, вторая ось 5 является осью запирающей планки 6, третья ось 7 является осью толкателя 8 запирающей планки 6. Преимущественно несущий корпус 1 выполнен в виде двух стенок, между которыми расположены оси и элементы механизма. Элемент спинки сиденья 4 содержит дугу зубьев 9. Запирающая планка 6 содержит дугу ответных зубьев 10, радиус которой соответствует радиусу дуги зубьев 9, и сквозные отверстия 11 и 12. В статическом положении предложенного механизма зубья 9 и 10 находятся в зацеплении, что обеспечивает угловую фиксацию спинки сиденья относительно его основания. Угол и радиус дуги зубьев 9 выбраны таким образом, чтобы обеспечить поворот спинки сиденья в диапазоне 180 градусов, что обеспечивает лежачее положение пассажира и полное складывание спинки вперед в ее крайних положениях. Зубья 9 и 10 могут иметь форму, как изображено на фиг. 1-3, либо иную форму. На фиг. 1- The specified mechanism comprises a supporting body 1, rigidly connected to the base of the seat 2 and located on one side of the seat. On the supporting body 1 there are three axes of pivotally fixed elements of the mechanism. The first axis 3 is the axis of the backrest element 4, the second axis 5 is the axis of the locking bar 6, the third axis 7 is the axis of the pusher 8 of the locking bar 6. Mostly, the bearing housing 1 is made in the form of two walls between which the axles and the elements of the mechanism are located. The backrest element 4 contains an arc of teeth 9. The locking bar 6 contains an arc of counter teeth 10, the radius of which corresponds to the radius of the arc of teeth 9, and through holes 11 and 12. In the static position of the proposed mechanism, the teeth 9 and 10 are engaged, which provides angular fixation seat backs relative to its base. The angle and radius of the arc of the teeth 9 are selected in such a way as to provide a rotation of the seatback in the range of 180 degrees, which ensures a lying position of the passenger and the folding of the backrest forward in its extreme positions. The teeth 9 and 10 may be shaped as shown in FIG. 1-3, or another form. In FIG. one-
3 одна сторона каждого зуба выполнена перпендикулярно касательной, соответствующей точке дуги. Такая форма зубьев 9 и 10 обеспечивает более надежное их зацепление, что в свою очередь также повышает надежность угловой фиксации спинки сиденья относительно его основания. Преимущественно элемент спинки сиденья выполнен монолитно (как показано на фиг. 1-3), однако возможен вариант исполнения, когда элемент спинки сиденья3, one side of each tooth is perpendicular to the tangent corresponding to the point of the arc. This shape of the teeth 9 and 10 provides a more reliable engagement, which in turn also increases the reliability of the angular fixation of the seatback relative to its base. Advantageously, the backrest element is made in one piece (as shown in Figs. 1-3), however, an embodiment is possible when the backrest element
4 представляет собой зубчатое колесо, жестко соединенное с планкой, которая в свою очередь закреплена на раме сиденья. Запирающая планка 6 с одной стороны шарнирно закреплена с зазором на оси 5, которая проходит через отверстие 12, а с другой стороны опирается на толкатель 8, который расположен в сквозном отверстии 11. Зазор между осью4 is a gear wheel rigidly connected to a bar, which in turn is mounted on a seat frame. The locking bar 6 on one side is pivotally fixed with a gap on the axis 5, which passes through the hole 12, and on the other hand rests on the pusher 8, which is located in the through hole 11. The gap between the axis
5 и поверхность^ отверстия 12 обеспечивает ход запирающей планки 6 при вращении толкателя 8. Толкатель 8 выполнен в виде круглого эксцентрика, а отверстие 11 имеет круглую форму того же диаметра. Толкатель 8 жестко соединен с рычагом (на фиг. не показано). Сиденье снабжено пружинным механизмом (например, газовыми пружинами), обеспечивающим самоподъем спинки сиденья в расцепленном положении зубьев 9 и 10 предложенного механизма. ОСУЩЕСТВЛЕНИЕ ИЗОБРЕТЕНИЯ 5 and the surface ^ of the hole 12 provides the stroke of the locking plate 6 during rotation of the pusher 8. The pusher 8 is made in the form of a circular eccentric, and the hole 11 has a round shape of the same diameter. The pusher 8 is rigidly connected to the lever (not shown in Fig.). The seat is equipped with a spring mechanism (for example, gas springs), which ensures self-raising of the seat back in the disengaged position of the teeth 9 and 10 of the proposed mechanism. DETAILED DESCRIPTION OF THE INVENTION
Предложенный механизм работает следующим образом. The proposed mechanism works as follows.
Для изменения угла наклона спинки человек, сидящий на сиденье, воздействует на рычаг, который поворачивает толкатель 8 вокруг его оси 7 по часовой стрелке. При вращении толкатель 8, выполненный в виде круглого эксцентрика, перемещает запирающую плацку 6 таким образом, что зубья 10 запирающей планки 6 выходят из зацепления с зубьями 9 элемента спинки сиденья 4. Далее воздействуют на спинку сиденья и выбирают нужный угол наклона. Для фиксации угла наклона спинки человек воздействует на рычаг, который поворачивает толкатель 8 вокруг оси 7 против часовой стрелки. Толкатель 8 в свою очередь перемещает запирающую планку 6, при этом ее зубья To change the angle of the backrest, a person sitting on a seat acts on a lever that rotates the pusher 8 around its axis 7 in a clockwise direction. During rotation, the pusher 8, made in the form of a circular eccentric, moves the locking plate 6 in such a way that the teeth 10 of the locking plate 6 disengage from the teeth 9 of the seat back element 4. Next, they act on the seat back and select the desired angle of inclination. To fix the angle of inclination of the back, a person acts on a lever that rotates the pusher 8 around axis 7 counterclockwise. The pusher 8, in turn, moves the locking bar 6, while its teeth
10 входят в зацепление с зубьями 9, что обеспечивает угловой фиксацию спинки сиденья. 10 engage with teeth 9, which provides angular fixation of the seatback.
Исполнение толкателя 8 в виде круглого эксцентрика, расположенного в круглом отверстии 11 запирающей планки 6 того же диаметра, обеспечивает максимальную площадь контакта толкателя 8 и внутренней поверхности отверстия 11. В случае высоких нагрузок на запирающую планку 6 нагрузка распределяется по всей площади контакта толкателя 8 с отверстием 11 запирающей планки 6, что исключает деформацию отверстия The execution of the pusher 8 in the form of a circular eccentric located in the round hole 11 of the locking plate 6 of the same diameter provides the maximum contact area of the pusher 8 and the inner surface of the hole 11. In the case of high loads on the locking plate 6, the load is distributed over the entire contact area of the pusher 8 with the hole 11 locking strips 6, which eliminates the deformation of the hole
11 или произвольный поворот толкателя 8. Очевидно, что такое исполнение позволяет повысить надежность угловой фиксации спинки сиденья относительно его основания. 11 or arbitrary rotation of the pusher 8. Obviously, this design improves the reliability of the angular fixation of the seatback relative to its base.
В отличие от сложной геометрической формы толкателя и фасонного отверстия запирающей планки прототипа круглая форма эксцентрика и отверстия запирающей планки предложенного механизма просты в изготовлении. Данный механизм может быть использован в устройствах иного назначения, в том числе в креслах и диванах домашнего назначения, в пассажирских креслах самолета, поезда и др.  In contrast to the complex geometric shape of the pusher and the shaped hole of the locking bar of the prototype, the circular shape of the eccentric and the hole of the locking bar of the proposed mechanism are simple to manufacture. This mechanism can be used in devices for other purposes, including in chairs and sofas for home use, in the passenger seats of an airplane, train, etc.
ПРОМЫШЛЕННАЯ ПРИМЕНИМОСТЬ INDUSTRIAL APPLICABILITY
Проведенные испытания показали, что данный механизм регулировки угла наклона спинки сиденья выдерживает повышенные нагрузки на спинку сиденья до 9 тонн включительно, что в свою очередь обеспечивает надежную угловую фиксацию спинки сиденья и повышает безопасность транспортного средства в целом. The tests showed that this mechanism for adjusting the angle of the seatback can withstand increased loads on the seatback up to 9 tons inclusive, which in turn provides reliable angular fixation of the seatback and increases the safety of the vehicle as a whole.
