Abstract

A car seat with a warning function includes a seat body having a seat cushion, plural adjusting posts, a wireless transmission module, a control unit and a warning element. The wireless transmission module is in wireless communication with an electronic device. When the adjusting posts are pushed by the seat cushion, the lengths of the adjusting posts are changed. If the control unit receives a body curve data from the electronic device and judges that the body curve data complies with a predetermined body data, the control unit changes the lengths of the adjusting posts according to the body curve information. Consequently, the shape of the seat cushion fits the body shape of the user. If the control unit judges that the body curve data does not comply with the predetermined body data, the control unit controls the warning element to output a warning signal.

First claim

What is claimed is:

1. A car seat with a warning function, the car seat being installed in a vehicle and comprising:
a seat body comprising a seat cushion, wherein the seat cushion is contactable with a human body of a user;
plural adjusting posts disposed within the seat body and contacted with the seat cushion, wherein a length of at least one adjusting post of the plural adjusting posts is changeable;
a wireless transmission module in wireless communication with an electronic device so as to receive a body curve data from the electronic device;
a control unit electrically connected with the plural adjusting posts and the wireless transmission module, wherein the control unit judges whether the body curve data complies with a predetermined body data; and
a warning element electrically connected with the control unit, wherein if the control unit judges that the body curve data does not comply with the predetermined body data, the warning element issues a warning signal, wherein if the control unit judges that the body curve data complies with the predetermined body data, the control unit adjusts the length of the at least one adjusting post according to the body curve data, so that a shape of the seat cushion fits a body shape of the human body of the user,
wherein when a car door of the vehicle is opened, the control unit judges whether the predetermined body data is stored in the car seat, wherein if the control unit judges that the predetermined body data has been stored in the car seat, the wireless transmission module is enabled to receive the body curve data, wherein if the control unit judges that the predetermined body data is not stored in the car seat, the control unit creates the predetermined body data,
wherein after the body curve data is received by the wireless transmission module, the control unit judges whether the body curve data complies with the predetermined body data, wherein if the body curve data is not received by the wireless transmission module, the control unit issues a password request signal to the electronic device through the wireless transmission module,
wherein after the electronic device outputs a user password in response to the password request signal, the control unit judges whether the user password complies with a predetermined password, wherein if the control unit judges that the user password complies with the predetermined password, the control unit enables plural detecting elements to detect the lengths of the plural adjusting posts, wherein if the control unit judges that the user password does not comply with the redetermined password, the control unit enables the warning element to output the warning signal.

2. The car seat according to claim 1 , wherein the car seat further comprises plural detecting elements, and the plural detecting elements are electrically connected with the plural adjusting posts and the control unit, wherein after the plural detecting elements detect length conditions of the plural adjusting posts, the plural detecting elements acquire plural pressure values and output the plural pressure values to the control unit.

3. The car seat according to claim 2 , wherein if the predetermined body data has not be created and the human body of the user is in contact with the seat cushion, the plural adjusting posts are pushed by the human body of the user and the length of the at least one adjusting post is changed, wherein after the plural detecting elements detect the length conditions of the plural adjusting posts, the plural detecting elements acquire the plural pressure values and output the plural pressure values to the control unit, wherein after the plural pressure values are received by the control unit, the control unit assigns an identity data to the plural pressure values in response to a confirmation signal, so that the predetermined body data is defined.

4. The car seat according to claim 3 , wherein the control unit issues the identity data and the plural pressure values to the electronic device through the wireless transmission module, so that the body curve data is defined.

5. The car seat according to claim 1 , wherein the at least one adjusting post comprises:
a retractable part disposed within the seat body and contacted with the seat cushion, wherein when the retractable part is pushed by the seat cushion, a length of the retractable part is shortened; and
a motive power element coupled with the retractable part and electrically connected with the control unit, wherein according to an adjusting signal from the control unit, the motive power element outputs motive power to the retractable part so as to adjust the length of the retractable part.

6. The car seat according to claim 5 , wherein the car set further comprises an adjusting key, and the adjusting key is electrically connected with the motive power element, wherein by operating the adjusting key, the motive power element is selectively controlled to output the motive power.

7. The car seat according to claim 1 , wherein while the warning element outputs the warning signal, the control unit issues a prompt message to the electronic device in response to the warning signal.
