Description

an elderly seat

technical field

The utility model relates to the technical field of seats, in particular to a chair for helping the elderly.

Background technique

At present, the design and service of auxiliary products for the elderly are the focus and difficulty of the elderly population. As the elderly gradually increase with age, the strength of the legs also gradually weakens. Because the speed and strength cannot be well controlled when getting up (especially after sitting for a long time) or sitting down, it is very easy to cause accidents such as falls, injuries, and spinal injuries for the elderly. In daily observation of the life and behavior habits of the elderly, it is found that most of the elderly suffer from damage to the legs and knee joints due to the degeneration of their body functions and the influence of some accumulated diseases, resulting in an unstable center of gravity when they sit down and difficulty getting up, especially in Getting up after sitting for a certain amount of time is especially problematic.

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides a seat for the elderly, which mainly solves the technical problems that the existing seat is inconvenient for the elderly to sit up.

To achieve the above object, the present invention is achieved through the following technical solutions:

A chair for helping the elderly, comprising a seat frame, two armrest assemblies, a seat cushion and an elastic member, the front end of the seat cushion is rotatably connected to the front end of the seat frame, the front end of the elastic member is rotatably connected to the bottom of the seat cushion, and the rear end of the elastic member is rotated It is connected to the rear end of the seat frame. Armrest brackets are arranged on both sides of the seat frame. The two armrest assemblies are respectively connected to the two armrest brackets in rotation. There is a limit chute in the limit part of the seat cushion, and a limit protrusion that can be slid in the limit chute is provided on both sides of the seat cushion, so that when the front end of the armrest is pressed down, the seat cushion limit part can drive the rear of the seat cushion. The end is raised upwards.

Further, a horizontally arranged connecting portion is provided at the bottom of the middle and rear ends of the seat cushion, a groove is provided in the middle of the connecting portion, and a connecting shaft is pierced through the connecting portion horizontally through the entire connecting portion, and the front end of the elastic piece is embedded in the connecting portion. The groove is rotatably connected to the connecting shaft, and both ends of the connecting shaft slightly protrude from both sides of the connecting portion to form limiting protrusions that can be slidably arranged in the limiting chute of the seat cushion limiting portion.

Further, two sides of the front end of the seat frame are respectively provided with a hinge portion, and the two sides of the front end of the seat cushion are respectively hinged to the corresponding hinge portions through a rotating shaft.

Further, the seat cushion limiting portion of the armrest assembly is inclined rearwardly and downwardly relative to the armrest.

Further, the length direction of the limit chute is consistent with the length direction of the seat cushion limit portion.

Further, a backrest is provided on the rear end of the seat frame.

Further, the elastic member is a gas spring.

The elderly assistance seat of the present invention has the following advantages:

The seat frame is provided with a seat cushion that can be rotated relative to the seat frame, and the front end of the seat cushion is rotatably connected to the front end of the seat frame, an elastic member is connected between the seat frame and the seat cushion, and the front end of the elastic member is rotatably connected On the bottom of the seat cushion, the rear end of the elastic member is rotatably connected to the rear end of the seat frame, and armrest assemblies are rotatably connected to the armrest brackets on both sides of the seat frame, and the bottom of the armrest assembly is inclined and provided with a cushion limiter A limit chute is set in the seat cushion limiting part, and a limit protrusion that can be slidably arranged in the limit chute is provided on both sides of the seat cushion. In the initial state, the rear end of the seat cushion will be lifted up under the elastic force of the elastic member. When a person sits down, the elastic force of the elastic member can buffer the human body to avoid the unstable center of gravity or movement when sitting down. Violently leads to too fast sitting and injury. When you need to get up, you only need to press down the front end of the armrest, and the armrest will drive the seat cushion limit part to move synchronously, so that the limit chute is raised as a whole, and then the limit chute is connected to the seat. The cooperation of the limit protrusions on both sides of the seat cushion lifts the rear end of the seat cushion upward, so as to achieve the effect of assisting getting up. At the same time, through the elastic action of the elastic member, the force required to press down the armrest when getting up can be effectively reduced, which is based on the principle of leverage. It can drive the front end of the seat cushion to rotate around the front end of the seat frame with a small force of the hand, so that the rear end of the seat cushion can be gradually raised, thereby reducing the requirement of leg strength when standing up, so as to help get up. Effect.
