Abstract
This invention provides a patient supporting device, such as a dental chair, that includes a stationary seat portion with movable backrest and toeboard portions, the chair being provided with a plurality of bladders to vary its contour. This includes bladders on the toeboard selectively inflatable to provide the effect of a deeper seat for the chair. Selectively inflatable bladders on the seat can simulate tilting of the seat when the back is lowered. Spaced bladders on the back support the lumbar region and the shoulders of the patient, and a third bladder on the back supports the patient's spine. Four bladders beneath pads are in the headrest, used in tilting the patient's head. An adustable edge portion for the back supports the patient's arms when in a supine position.
Claims26
A device for supporting a patient comprising
- seat means,
- backrest means having bottom, top and side edges,
- inflatable means on said backrest means for varying the surface contour thereof, said inflatable means including,
- a first bladder means adjacent said bottom edge of said backrest means,
- a second bladder means spaced inwardly from said side edges of said backrest means and extending longitudinally of said backrest means substantially at the center thereof,
- and means for selectively inflating said bladders of said inflatable means.
A device for supporting a patient comprising
- seat means,
- backrest means,
- toeboard means connected to said seat means and extending therefrom at an angle relative thereto,
- at least one inflatable means on said toeboard means adjacent said seat means,
- and means for selectively inflating said inflatable means for providing a protuberance on said toeboard means to act as an extension of said seat means.
A device for supporting a patient comprising
- seat means,
- and support means extending from said seat means for providing a backrest and a headrest, said support means including
- a support member,
- a central pad on said support member for engagement by a patient's head,
- a plurality of additional pads positioned around said central pad so that each of said additional pads has an edge adjacent said central pad,
- hinge means connecting each of said edges of additional pads to said support member,
- a bladder on said support member beneath each of said additional pads,
- and means for selectively inflating said bladders for selectively pivoting said additional pads outwardly around said hinge means.
A device for supporting a patient comprising
- seat means,
- backrest means extending from one end of said seat means and having an outer edge remote from said seat means,
- toeboard means extending from the opposite end of said seat means,
- a headrest on said backrest means beyond said outer edge thereof, said headrest including
- a support,
- a central pad,
- four additional pads,
- and means connecting said four additional pads to said support adjacent and around the periphery of said central pad so as to provide a top, a bottom, and two side pads for said headrest with the corners of said additional pads in adjacency,
- and inflatable means for varying the surface contour of said device, said inflatable means including
- a first transverse bladder on said backrest means adjacent said seat means,
- a second transverse bladder on said backrest means spaced from said first transverse bladder and adjacent said outer edge of said backrest means,
- a central bladder on said backrest means extending from adjacent said outer edge thereof to adjacent said first bladder,
- a bladder beneath each of said additional pads of said headrest for moving each of said additional pads outwardly upon inflation thereof,
- at least one transverse bladder on said toeboard means adjacent said seat means for providing the effect of a continuation of said seat means upon inflation thereof,
- a plurality of transverse bladders on said seat means extending inwardly from said end adjacent said toeboard means, and means for selectively inflating said bladders.
