Изобретение отнсюитс к MamraiocTpoeнию и может быть использовано как опорный элемент в конструкци х, где на любых участках может создаватьс кривизна большего или меньшего радиуса и при этом5 не надо использовать какие-либо дополнительные приспособлени нат га.
Наиболее близкой к предлагаемой по технической сущности вл етс опора дл спинок кресел, содержаща амортизирующиеЮ элементы, размешенные под ними основную опорную ленту, управл емую манипул тором, один конец которой жестко закреплен на одном из амортизируюших элементах, и нат жное устройство, св занное с другим 18 концом основной опорной ленты tl
Недостатком известной опоры вл етс то, что при эксплуатации нат жное устройство выходит из стро и его приходитс мен ть.20
Цель изобретени - улучшение условий эксплуатации опоры.
Указанна цель достигаетс тем, что опора дл спинок кресел, содержаша амортизирующие элементы, размешенные 25
(54) ОПОРА
под нимд основную опорную ленту, jTipaBл емую машшул тором, один конец которой жестко закреплен на одном из амор)- ТИ31ФУКЛЦИХ элементов, и нат жное устройство , св занное с другим концом основной опорной ленты, снабжена допошштельной опорной лентой, установленной параллельно основной, двум нат жными лентами, раз- мещеннымЕ под опорными регулируемыми фижсаторами, установленными по длине опорных к нат жнь(х лент с возможностью перемещени вдоль них, нат жное устро-t ство выпо нено в виде двух пар пластин, посредством одной из которых соединены между собой опорные ленты, посредством другой - нат жные, взаимодействующие с пластинами через рычаги винта.
Кроме того, фиксаторы вьшолнены в ввде скоб, двойных (соосных) заклепок тши винтов, гильз или шайб.
На чертеже изображена предлагаема опора, обивай вид.

- Опора содержит утфавл емую манипул тором 1 опорную ленту 2 и дополните ную опорную ленту 3, амортизирующий элемент, выполненный в виде перемычек 4 - 9, нат жное устройство 10, выполненное в виде рычажных ножшщ, нат жные ленты 11 и 12, размеще1шые под опорными лентами 2 и 3, и фиксаторы 13 и 14, установленные по ДJПшe опорных 2 и 3 и нат жных 12 и 11 лент. Устройство работает следующим образом . При повороте винта 15 посредством руко тки или маховика (не показано) в .направлении стрелки 16 рычаги 17 - 20 перейдут в свое нат нутое положение ; так, что шарнирно св занные с ними перемычки 9 отойдут или отожмутс одна от другой, передава усили ;ш нат жные ленты 12 и 11, которые изогнут опорны ленты 2 и 3. Предлагаемые опоры могут быть использованы в сшгаках кресел и в сидень автомобил . Манипул тором 1 получают удобную подгонку кривизны сшшки в фор ме спины сид шего. При этом степень кривизны можно отрегулировать поворотом также 5боку расположенной насажен ной на винт ручки (не показано). Формула изобре тени 1. Опора дл спинок кресел, содержаща амортизирующие элементы, размещен ные под ними основную опорную ленту, управл емую манипул тором, один конец которой жестко закреплен на одном из Амортизирующих элементов, и нат жное устройство, св занное с другим концом основной опорной ленты, отличающ а с тем, что, с целью улучшени условий эксплуатации, она снабжена дополнительной опорной лентой, установленной параллельно основной, двум нат жными лентами, размещенными под опорными регулируемыми фиксаторами, установленными по длине опорных и нат жных лент с возможностью перемещени вдоль них, а нат жное устройство выполнено в виде двух пар пластин, посредством одной из которых соединены между собой опорные ленты, посредством другой - нат жные, взаимодействующие с пластинами через рычаги винта.
- 2. Опора по п. 1, о т л и ч а ю щ а с тем, что фиксаторы выполнень в виде скоб, двойных (соосных) заклепо впи винтов, гильз или шайб. Источники информации, прин тые во внимание при экспертизе 1. Авторское свидетельство СССР № 361787, кл. & 60N 1/02, 197О (прототип).
