    • A lifting device, particularly for a dentist chair incorporating support arms arranged in a scissor form between a base portion and a seat support portion which is height adjustable relative thereto. The scissor action support mechanism comprises two support arms arranged in a single scissor's pair to realize an extremely compact yet rugged design. Each support arm includes two arm parts - a shorter arm and a longer arm - which are joined at one of their ends by a lateral stiffening section. The two support arms are arranged to face each other and are joined by an axle bearing which ties the two shorter arm parts to each other thus creating the scissor lifting structure. The free ends of the longer arms are mounted on lower and upper horizontal guides. A spindle driver applying forces at or near the axle bearing is used for lowering or raising the seat. The scissor arms are fully collapsible and because of the double arm construction a rugged, tension-stiff assembly results.
    • 提升装置,特别是用于在基座部分和座椅支撑部分之间以剪刀形式布置的支撑臂的牙科椅子,其可相对于其高度可调节。 剪刀动作支撑机构包括设置在单个剪刀对中的两个支撑臂,以实现非常紧凑而坚固的设计。 每个支撑臂包括两个臂部分 - 一个较短的臂和一个较长的臂 - 它们的一端由侧向加强部分连接。 两个支撑臂被布置成彼此面对并且通过将两个较短臂部彼此连接的车轴支承件相连,从而产生剪刀提升结构。 较长臂的自由端安装在上下水平导轨上。 用于在轴承处或附近施加力的主轴驱动器用于降低或升高座椅。 剪刀臂完全可折叠,并且由于双臂结构,结果是坚固的,拉紧的组装结果。

    • A dental chair having a support frame, a seat with a seat frame, a back rest pivotally connected to the seat and a displacement device for moving the seat frame on the support frame with tilting of the seat and an arrangement for controlling the inclination of the back rest, characterized by the pivotal connection between the seat comprising a separate pivoting bearing on each side having a pivot axis approximately in the area of the hip joint of a person sitting in the chair and the arrangement for controlling the inclination of the back rest comprising a one-piece member having two lever arms being pivotally connected on the side of the seat frame with one of the lever arms having a roller riding on the track on the support frame and the other lever arm being connected to a projection of a part of the pivoting bearing which is attached to the seat rest so that as the seat frame is moved between positions, the roller moving on the track enables the back to change its degree of inclination to the seat. The chair also includes an arrangement for tilting the seat which includes at least one pair of guide members which are inclined to each other by approximately 160.degree. and are mounted in the seat frame, which guide members receive sleeves that are pivotally connected to the support frame.
    • 一种具有支撑框架的座椅,具有座椅框架的座椅,枢转地连接到座椅的靠背和用于使座椅的倾斜将座椅框架移动到支撑框架上的移动装置,以及用于控制座椅的倾斜的装置 其特征在于,所述座椅之间的枢转连接包括在每侧上的单独的枢转轴承,所述枢转轴线具有大致在坐在椅子上的人的髋关节的区域中的枢转轴线以及用于控制靠背的倾斜的装置,其包括 具有两个杠杆臂的单件构件,其在所述座椅框架的侧面枢转地连接,所述杠杆臂中的一个具有骑在所述支撑框架上的轨道上的辊,并且所述另一个杠杆臂连接到所述支架的一部分的突出部 连接到座椅的枢转轴承使得当座椅框架在位置之间移动时,在轨道上移动的滚轮使得背部能够改变其倾斜度 到座位。 椅子还包括一个用于倾斜座椅的装置,该装置包括彼此相对倾斜约160°的至少一对导向件,并且安装在座椅框架中,这些导向构件接受枢转地连接到支撑框架的套筒 。

    • The invention is directed to an adjustable head support for a dental treatment chair, which is a reclining chair with an adjustable head rest or support. In order to better match the kinematics of the adjustable head support to a natural tilting motion of a patient's head, it is proposed that a quadrilateral linkage pivotally connects an upper region of the back rest to the head rest and the connection of the linkage to the head rest is shifted as the head rest tilts to cause a point on the head rest to move in an arc having a center roughly in the cervical vertebra joint of the patient lying in the chair.
    • 本发明涉及一种用于牙科治疗椅的可调头部支撑件,其是具有可调头枕或支撑件的躺椅。 为了更好地将可调节头部支撑件的运动学与患者头部的自然倾斜运动相匹配,提出了一种四边形连杆枢转地将靠背的上部区域枢转地连接到头枕上,并且将连接件连接到 当头枕倾斜时,头枕移动,使得头枕上的点在具有大致在位于椅子中的患者的颈椎关节中的大致弧形的弧中移动。

    • The invention relates to a dentist chair with a chair top carrying at least a chair seat. A chair bottom contains a height-adjusting system for the chair top, and at least one apparatus adaptable at the chair bottom which requires various supplies, such as air, water, electric current, which by means of supply lines are brought into the apparatus through the chair bottom from a connection box at the floor. For hookup of the apparatus the chair bottom contains a hookup portion which contains coupling means both for mechanical coupling and for coupling of the various other supply lines. The apparatus is connectible to the supply lines through a counter-piece which matches the hookup portion of the chair bottom and which, for mechanical coupling of the apparatus contains counter-coupling means which can be brought into engagement with the coupling means and which then establishes the proper required connection.
