Definitions

  • the invention relates to a dental patient chair with a swivel-mounted backrest, which consists essentially of a 1-shaped supporting part, the transverse web of which connects to the rear edge of the chair seat and is connected to it via a joint, and an upholstered pad arranged thereon and which at least in its lower half has a free space directed towards the central backrest axis with a width in the direction of the longitudinal axis of the chair of at least the knee width of an average person.
  • Such a patient chair is known for example from US-A-2 341 465 or DE-A1-2 436 211.
  • the actual backrest is not fully supported on the central web; rather, it is connected to it only at one point by means of a connecting joint.
  • the backrest In order to be able to absorb the weight load, the backrest must therefore have its own stable support frame over its entire length and width, on which the relatively soft cushion cover can rest.
  • Such constructions are structurally complex and lead to relatively thick walls, specifically in the area of the backrest that has to be passed under the knees of the practitioner when the backrest is strongly inclined.
  • the known chair designs also have armrests on both sides of the seat; in one construction, these are articulated on the crossbar of the supporting part and thus serve to hold or guide the backrest. A frequently expressed customer request that the entry and exit side of the chair be free from any armrest construction can therefore not be met with these known constructions.
  • This is possible with another known chair construction (DE-B2-2121 992); However, this chair does not contain any armrests at all, rather parts supporting the elbows and upper arms of a patient are molded onto the backrest on both sides.
  • the object of the present invention is to provide a dental patient chair of the type mentioned at the outset which, on the one hand, enables the backrest to be adequately passed under the knees in the lying positions without direct contact with the patient, and which, on the other hand, allows the second armrest to be used if necessary to waive or to be able to hold them easily if necessary.
  • the central web of the supporting part extends to the upper edge of the backrest and on it a flat, corresponding to the backrest width and extending to the seat surface, a relatively thin padding rests, and in the upper backrest half of the same size on both sides of the central web are attached to this, at least one of which contains a bearing bush for the armrest and the other is removably held on the central web.
  • FIG. 1 shows a diagrammatic representation, diagonally from the rear, of a dental patient chair with a lower chair part 1 and an upper chair part 2 arranged thereon, which essentially consists of a seat 3 and a backrest 4.
  • the backrest 4 is pivotally mounted on the seat 3 by means of a connecting joint 5.
  • the backrest 4 essentially consists of a 1-shaped base support frame 6 with side parts 7, 8 attached to it in the upper area and a relatively thin cushion cover 9 (FIG. 2) placed on the front side of the backrest.
  • the transverse web 10 of the support frame 6 is articulated on both sides of the chair by means of the connecting joint 5 on the seat and runs harmoniously into a central web 11 reaching to the upper edge of the backrest (FIG. 2).
  • a support rod 12 is adjustably supported for a head cushion 13.
  • the two side parts 7, 8 and the ends of the crosspiece 10 form indentations 14 (FIG. 1) on both sides in the lower half of the backrest, which are covered by the cushion cover 9.
  • the indentations 14 extend in the direction of the longitudinal axis 15 of the chair over a width a which corresponds approximately to the knee width of an average person and transversely to the longitudinal axis 15 of the chair over a depth b which is approximately a quarter to a third of the backrest width B corresponds.
  • the width of the central web 11 is at a depth of one
  • a third of the backrest width also has a web width of one third of the backrest width.
  • Armrests or armrests 16 are articulated on the two side parts 7, 8.
  • FIG. 2 shows the chair shown in FIG. 1 with the right side part 8 removed. It can be seen from the illustration that this results in an indentation which extends to the upper edge of the backrest and which allows the backrest to be passed underneath for one on the right side of the chair working practitioners practically from 9:00 a.m. to 11:00 a.m. If the patient is to be treated in a 9:00 o'clock position, that is to say if the backrest is strongly inclined, the practitioner must place himself at the head end of the chair, it is also advantageous to remove the left side part 7. In this way, the practitioner can place both legs under the backrest, the distance between the patient and the practitioner being extremely close, but without direct contact between the practitioner and the patient in the lying area.
  • the support frame 6 provides the required stability, whereas the cushion cover only serves for even surface support or support.
  • the cushion cover is therefore relatively thin compared to the support frame;
  • a stiffener This can e.g. B. consist of a resilient insert or from a corresponding preloaded spring core. It is advantageous to design the cushion cover so that it is elastic towards the front, ie towards the patient, but largely stiff towards the rear.
  • two shoulders 18 for shoulder support can be arranged laterally in the upper region of the cushion pad.
  • this shoulder support is part of the cushion pad, which for this purpose has a stiffened rear wall or insert made of an elastic plastic, e.g. B. polystyrene, or other resilient material.
  • FIG. 4 shows a section of the backrest seen from the front with the cushion cover 9 removed and reveals the connection of the side parts to the central web 11.
  • tabs 20 are provided on both sides, which are welded to the support parts 21 and releasably attached to the central web 11.
  • Bearing bushes 19 for mounting the armrests 16 are also arranged on the supporting parts 21.
  • the cushion pad 9 which e.g. with the help of a Velcro strap or the like. is attached to the support frame 6 to be removed.
